What is general purpose polystyrene?

General purpose polystyrene (GPPS) is one of the most widely used kinds of plastic that has excellent transparency, high stiffness and excellent moldability (injection, extrusion, foam molding, etc.).

What is the difference between PS and HIPS?

As the name would suggest, HIPS is a form of PS that carries with it a higher impact strength. Homopolymer PS can often be brittle, and can be made more impact resistant if combined with other materials. This form of PS typically is produced by adding around 5-10% rubber or butadiene copolymer.

What type of plastic is PS?

Polystyrene (PS) plastic is a naturally transparent thermoplastic that is available as both a typical solid plastic as well in the form of a rigid foam material.

What is meant by high impact polystyrene?

High Impact Polystyrene (HIS) is a low cost, tough plastic that is easy to thermoform and fabricate. HIS is often used for countertop point of purchase displays and indoor signs where ease of fabrication is essential.

What EPS used for?

EPS is a vector file format often required for professional and high-quality image printing. PostScript printers and image setters typically use EPS to produce vast, detailed images — such as billboard advertising, large posters, and attention-grabbing marketing collateral.

What is the difference between PP and PET?

PP stands for polypropylene while PET stands for polyethylene terephthalate. The key difference between PP and PET is that PP is a saturated polymer, whereas PET is an unsaturated polymer.

What are the properties of polystyrene?

Polystyrene Characteristics Unmodified polystyrene is clear, rigid, brittle and moderately strong. Its electrical properties as a dielectric material are good, though it has relatively low heat resistance. Polystyrene is soluble in most chlorinated and aromatic solvents, though not in alcohols.

What is the difference between PP and ABS?

ABS is impact resistant, which means it has better toughness than PP. The temperature resistance of ABS is also better than PP’s. Both ABS and PP have shiny surfaces, and the surface of ABS is shinier than PP’s.

What is the difference between ABS and GRP?

ABS covers better withstand the vibration of rough roads whereas Fiberglass is prone to crack under the shock of rough terrain. As well, in many impact situations where Fiberglass will crack or shatter, ABS will survive unscathed, although minor damage to both materials can be repaired.

What is EPS and its types?

Reported EPS or GAAP EPS is the earnings figure derived from generally accepted accounting principles (GAAP). Ongoing or pro forma EPS excludes unusual one-time company gains or losses. Carry value or book value EPS is the real cash worth of each share of company stock.

What is EPS Basic?

Basic earnings per share (EPS) tells investors how much of a firm’s net income was allotted to each share of common stock. It is reported in a company’s income statement and is especially informative for businesses with only common stock in their capital structures.
