ABS plastic and PS plastic Q: Which is better, ABS plastic or PS plastic?

A: In general, ABS plastic performance is better than PS plastic, you can do with PS plastic products, ABS plastic can generally be played out, and with ABS raw materials can do products, PS raw materials may not be made.

If you want to compare that you have to set a premise, because ABS plastic has flame retardant ABS, weather resistant ABS plastic and so on, PS has enhanced PS plastic, toughened PS and so on. Below we have a comprehensive analysis of ordinary ABS plastics and PS plastics.

ABS plastic and PP plastic are olefin products, ABS plastic comprehensive performance is stronger than PS plastic, you look at the price, ABS plastic price per ton is many thousands of higher than PS plastic

ABS is an alloying product of acrylic styrene butadiene, and PP is polystyrene, which means that ABS plastic itself has some characteristics of PS plastic, and there are more other characteristics compared with PP plastic. ABS plastic is better than PP plastic in terms of toughness, temperature resistance is slightly higher than PP plastic, and the appearance gloss is also superior to PS plastic.

If you want to compare ABS plastic and PP plastic which is good, we have to set a premise, ABS plastic has good rigidity, high impact strength, heat resistance, low temperature resistance, chemical resistance, mechanical strength and electrical performance, easy to process, processing dimensional stability and surface luster is good, easy to paint, color, It can also perform secondary processing properties such as spraying metal, electroplating, welding and bonding. Main applications of ABS plastics: automobiles, appliances, electronics/appliances, building materials, ABS alloys/blends.

PS plastic is a general grade polystyrene is a thermoplastic resin. It is harder than PP plastic and has a higher melting point. Because polystyrene is very brittle at temperatures above 0 ° C, many commercial PPS materials are random copolymers with 1 to 4% ethylene added or clip-on copolymers with higher ratios of ethylene content. Copolymer PP materials have a lower thermal distortion temperature (100 ° C), higher transparency, low gloss, low rigidity, but have a stronger impact strength. The impact strength of PP plastic increases with the increase of ethylene content.

The Vica softening temperature of PS plastic is 180℃. Due to the high crystallinity, the surface stiffness and scratch resistance of this material are good. frpp tubes do not have environmental stress cracking problems. PS plastics are usually modified by adding glass fiber, metal additives or thermoplastic rubber. The MFR of PS plastic flow rate ranges from 1 to 40. PP materials with low MFR have better impact resistance but lower tensile strength. For the same MFR material, the use of PS alone for products, brittleness, and in PS to add a small amount of other substances, such as butadiene can significantly reduce brittleness, improve the impact toughness, this plastic is called impact resistance PS, its mechanical properties are greatly improved, can be made of this plastic to produce many excellent mechanical parts and components.
