Coir is a natural fibre extracted from between the hard, internal shell and the husk of coconuts. Brown coir, which is made from ripe coconuts, is used in products such as upholstery padding, floor mats, doormats, brushes, mattresses, sacking, and horticulture.
White coir, harvested from unripe coconuts, is often used to make finer brushes, string, rope and fishing nets.
White coir doesn’t sink in water, so can be used in deep water without dragging down boats and buoys.
Coir fibre is one of the few natural fibres that are resistant to saltwater damage and are waterproof. In fact, water is used to process coir; fresh water is used to process brown coir and sea water and fresh water are used to produce white coir.
Ground coir fibres are also widely used in filtration.
Milled coir natural fibres (flock)
Coconut shell coir flock is often used as a base material in filtration systems such as activated carbon filters.
Coir is microporous and hardy, so is very efficient at absorbing organic chemicals, pesticides and herbicides, disinfection by-products, and improving the appearance and taste of drinking water.
For this reason, these flocks are often used in water filters, although they can also be used in other types of filter.
Milled coir flocks are able to filter out common particulates and impurities such as dirt, sand, fine sediment, rust, limescale, and silt.
Coconut shells are also an eco-friendly and renewable resource, able to filter several materials in a natural and chemical-free way.
We offer coir flock in the following sizes:
- 500 – 1000 microns
