Engineering Polymers , armed with properties like high dimensional stability, good strength, heat and chemical resistant, are widely being used as a substitute for metal across industries. The Consumer Durables and White Goods/ Appliances market, automotive and transportation industry are the biggest end-use market of Engineering Plastics.

ABS (Acrylonitrile Butadienestyrene)
Acrylonitrile Butadienestyrene, popularly known as ABS granules is an engineering polymer that has great fluidity to take up any shape, and provides a good shine and colour. ABS stands out for its strong nature, thermal stability and its ability to conform to any rigid matrix. The most important properties of ABS are its durability and impact resistance feature, although various modifications can be made to amplify these properties. ABS has excellent stability under limited loads, and displays valuable characteristics within -20 °C to 80 °C.
Salient Features:-
• Perfect finish
• Quality approved
• Different shapes

GPPS (General-purpose Polystyrene)
General-purpose Polystyrene, also known as GPPS is a substance prepared from styrene monomer polymer. It is a solid, transparent product and is manufactured by a suspension process. It is also known as crystal-clear polystyrene and is very different from high impact Polystyrene (HIPS). GPPS is converted into a range of products by converting it into granular form.
Brittle, rigid, transparent, low shrinkage, low cost, excellent X-ray resistance, free from odour and taste, easy to process

Tensile Strength 2.30 – 3.60 N/mm²
Notched Impact Strength 2.0 – 2.5 Kj/m²
Thermal Coefficient of expansion 80 x 10-6
Max Cont Use Temp 70 – 85 oC
Density 1.05 g/cm3

HIPS (High Impact Polystyrene)
High Impact Polystyrene is a plastic material that is inexpensive and used for structural applications that demand low strength. It is tough and rigid with high impact strength. It is employed in applications where it can be guillotined, punched, routered, or sawn with ease. The manufacturing process of HIPS involves several stages. First, the raw material is taken in a feed tank where it is lubricated, toned, and properly mixed.
Hard, rigid, translucent, impact strength up to 7 x GPPS, other properties similar.

Tensile Strength 2.20 – 2.70 N/mm²
Notched Impact Strength 10.0 – 20.0 Kj/m²
Thermal Coefficient of expansion 80 x 10-6
Max Cont Use Temp 60 – 80 oC
Density 1.03 – 1.06 g/cm3

PC (Polycarbonate)
Polycarbonates area group of Engineering Thermoplastic Polymers. They are essentially polymers containing carbonate groups. The production process of polycarbonates mainly involves producing a reaction between Bisphenol A and Phosge. They are naturally thermoplastic and are widely popular for their impact resistance and thermo plastic properties.
Polycarbonate is a durable material. Although it has high impact-resistance, it has low scratch-resistance. Therefore, a hard coating is applied to polycarbonate eyewear lenses and polycarbonate exterior automotive components.
