What is composite?

Composite, or commonly called Fibre-reinforced plastics are a class of materials in which the basic

properties of plastics (such as lightness in weight, very good moudability, excellent resistance to chemical

corrosion, and excellent electrical insulation) are given mechanical reinforcement by addition of fibrous

materials such as glass, cellulose, synthetic fibres, carbon and boron.

Since the first plastics were commercialized, there has been a need for additives to make the early resins

processable in the first place and, subsequently, to improve the properties of the moulded product during use.

As the scope of plastics has increased, so has the range of additives: for better mechanical properties, resistance to heat, light and weathering, flame-retardancy, electrical conductivity.

With better understanding of the mechanism by which the specific functions are achieved, products have been

steadily refined so that today the actual amount of the additive used in plastics can be reduced in some cases

to fractions of a percentage.

DELTA specialties offer additives for the following systems:

• Unsaturated polyesters, Gelcoats and Epoxies (SMC/BMC, Pultrusion and Filament winding)

• PVC and plasticized-pastes

• Polyurethanes
