Construction

block cutout bottom

Goonvean Fibres produces short cut polyester, polypropylene, and nylon construction fibres that are often used in a wide range of concrete and insulation applications.

These construction fibres add structural integrity to composite materials, adding extra high performance properties to building materials. Fibres can minimise shrinkage on drying, improve the tensile strength, and enhance permeability.

Please use the configurator below so we can recommend a product based on your requirements.

Concrete

Construction Fibres are added to concrete mix to minimise shrinkage, reduce risk of cracks, and to improve green strength. Alongside the concrete reinforcement, fibres in concrete add permeability by producing tiny channels in the castable structure. Improvements in permeability aids drying and helps to prevent explosive spalling.

We offer the following fibres and flocks for concrete construction:

100 – 500 microns

Natural ground olive stones are odourless organic materials ground to fine flours, granules and pits. These inexpensive natural materials are used to improve the thermal insulation of concrete, cement, and mortar, as well as to improve grip and anti-sag properties.

< 500 microns

2.10 decitex

Nylon can be added to concrete to reduce its permeability to water and chemicals. This is because nylon is resistant to ground chemicals and water. It also holds concrete together should it crack or wear.

3.30 decitex

Polyester has excellent weather-proof and fire-retardant qualities, which improve the performance of concrete applications and creates a smooth and level surface that water and dirt cannot penetrate. It is also very lightweight, meaning that polyester concrete can be used to create complex 3D shapes.

3.30 decitex

Polypropylene (PP) is a thermoplastic polymer that is often used to improve the flexural strength of concrete. It is rugged and unusually resistant to many chemical solvents, bases and acids making it an ideal material for use in concrete.

Insulation

We offer a variety of precision or short cut fibres and ground flocks for use in the manufacture of insulation products. Nylon, polypropylene, and polyester can be used in the fabrication of plasterboard. Natural flocks such as wool and hemp are used for wall, loft, and underfloor insulation.

Insulation materials include:

1.70 decitex

3.30 decitex

Precision cut polyester fibre is a very strong and stable man made fibre that is used in many industries. It is warm and insulating, making it perfect for most insulation applications. Polyester is resistant to stretching and shrinking and very resistant to abrasion and acid degradation.

2.10 decitex

Nylon is widely used in industrial applications as it is insulating, strong, and very stable. It is great for insulation purposes as it is breathable but tightly woven.

3.30 decitex

28.00 decitex

Viscose rayon is 100% biodegradable and so it is also widely used in environmentally friendly applications. It is a good eco-friendly alternative to other insulation fibres.

 

Adhesives

Adhesives are commonly used across a wide range of industries and applications. Fibres are added to adhesives to increase binding ability, distribute stress more efficiently across the join, reduce cost, and increase design flexibility.

The following materials are available for adhesive applications:

< 100 microns

Polypropylene is a strong and flexible plastic that is used in many applications. Polypropylene glues and adhesives are used to adhere lots of different types of plastic, as they are incredibly versatile and durable.

< 100 microns 

100 – 500 microns 

Much like polypropylene adhesive, polyethylene is used for the adhesion of other polyethylene plastics.
Polyethylene has high impact strength, is resistant to chemicals, solvents, and impact, has good fatigue and wear resistance, has zero water absorption, and is very flexible.

< 500 microns

Cotton is a strong and environmentally-friendly material which can be added to adhesive formulations to increase flexibility, durability, and longevity.

1001 – 5000 microns

Resorcinol Formaldehyde Latex (RFL) coated polyester is coated with RFL to improve adhesive properties of polyester.

3.30 decitex

Polyester is resistant to stretching, shrinking, abrasion, and acid degradation, making it an excellent addition to adhesives.

3.30 decitex

6.70 decitex

Acrylic fibres are strong and flexible, making them a good addition to adhesives, paints, and coatings. Short cut fibres are ideal for crack bridging and covering uneven surfaces.

3.30 decitex

17.00 decitex

Modacrylic is strong, soft, resilient, and flexible, making it a popular addition to adhesives. It also disperses readily.

They have outstanding resistance to chemicals, solvents, and high temperature, as well as being hard to burn. For this reason, it is commonly used as an intumescent material in adhesives, resins, and paints.

Sealants

Short cut fibres, flocks and powders are used as flexible reinforcement in many sealant formulations. They provide a durable bond for years whilst at the same time providing flexibility.

For aggressive environments where major maintenance downtime is not immediately possible, e.g. chemical transfer pipework, sealing compounds containing short cut fibres provide a product that will withstand extremely high temperatures and levels of abrasion and corrosion.

Fibres and powders are also widely used in the manufacture of tyre puncture sealants, which provide a permanent repair for almost any tyre.

The following materials are used in sealants:

< 500 microns

500 – 1000 microns

1001 – 5000 microns

> 5000 microns

Polyethylene flock is used in sealants due to its high impact strength and resistance to chemicals and solvents. It is also extremely flexible and absorbs zero water, making it a common choice for marine applications.

2.10 decitex

Nylon is often added to sealant mixtures as it is hard wearing and durable, sunlight and sun damage resistant, resistant to high temperatures and abrasion, and easily dispersible.

3.30 decitex

Polypropylene is extremely tough, durable, and flexible, making it a good choice for sealant manufacture. It has the ability to flex with the finished product without letting in water, air, or other unwanted particles.

< 500 microns

500 – 1000 microns

1001 – 5000 microns

> 5000 microns 

Aramid fibres are strong, heat resistant, and help to improve viscosity control for sealants. The material disperses well throughout liquids and settles in a random pattern, thickening or building viscosity. This is unaffected by processing or aging.

< 500 microns

500 – 1000 microns

1001 – 5000 microns

Acrylic sealant is often made from acrylic resins and is used for caulking, jointing, and filling cracks and gaps. It is commonly used in the construction industry, but can also be for commercial use.

Acrylic sealant protects surfaces from dust and insects and it stays flexible even after you paint it. When it is cured, it becomes like rubber in that it is very flexible and durable. This makes it popular for construction applications as building joints need to have the ability to move slightly. Also, acrylic can be easily painted over, making acrylic sealant ideal for interior and exterior decoration.

Modacrylic is strong, soft, resilient, and flexible, making it a popular addition to adhesives. It also disperses readily.

They have outstanding resistance to chemicals, solvents, and high temperature, as well as being hard to burn. For this reason, it is commonly used as an intumescent material in adhesives, resins, and paints.

Resins

Goonvean Fibres produces a range of short cut fibers that can be used to improve the physical properties of the base resin.
When combined with fibres and flocks, resins gain higher tensile strength, toughness, and malleability. When combined, fibres and resins can counteract the other’s weakness, producing a material far more useful than its individual components.

The following fibres and flocks can be added to reinforce resins:

< 100 microns

Polypropylene is a type of thermoplastic polymer resin.

It is lightweight and very flexible, making it less likely to shatter. Polypropylene also has the ability to take significant damage before breaking.

Polypropylene is also easy to customize, since it has a high dye affinity.

It also does not absorb water like other plastics.

100 – 500 microns

Olive stones are often used to add anti-slip properties to resins and other construction materials.

< 100 microns

100 – 500 microns

Polyethylene resin is often used in the construction industry as a flexible yet durable material.

It has mechanical, thermal, chemical, and electrical. It absorbs almost no water and burns slowly.
