ABS engineering plastics with excellent comprehensive properties, has excellent impact strength, good dimensional stability, electrical properties, abrasion resistance, chemical resistance, stain resistance, molding processing and mechanical processing good ABS resin water, inorganic salts, alkalis and acids, insoluble in most alcohols and hydrocarbon solvents, and easily soluble in aldehyde, ketone, ester and some chlorinated hydrocarbons.
ABS engineering plastics shortcomings: thermal deformation temperature is low, flammable, poor weather resistance.
Use: suitable for making general mechanical parts, reduce wear and wear resistant parts, transmission parts and telecommunications parts.

PC ABS,
Commonly known as ABS and polycarbonate. Is one of the domestic minority several possible through the use of material, not spontaneous combustion, fire burning, the surface of like poly carbon burning like small precipitates, black below the ABS, common in electronics, machinery spare parts, etc.
Polyamide (PA, commonly known as nylon)
PA is characteristic: tough, strong, wear-resistant, non-toxic.
Disadvantages: can not be long-term contact with acid and alkali.
Commonly used in the production of comb, toothbrush, rope bag, hook, a fan, fruit bags and so on.
PC is the abbreviation of polycarbonate, polycarbonate in English is Polycarbonate, referred to as PC engineering plastics, PC materials, in fact, we are said to be one of the engineering plastics, as widely used in the world wide range of materials,
Colorless and transparent polycarbonate, heat, impact resistant, flame retardant, in common use temperature have good mechanical properties. The same compared to PMMA, polycarbonate good impact resistance, high refractive index, processing performance,
The wear resistance of polycarbonate is poor. Some polycarbonate devices used for easy wear and tear use need to be specially treated on the surface.
Common application with a CD, the eyes, Aquarius, bulletproof glass, goggles, bank anti bullet glass, headlights and so on, animal cages pet cages.
Polycarbonate is also used to make the moon astronaut's helmet mask. The iPod music player and the iBook notebook computer shell of the Apple Corp are also made of polycarbonate.

PMMA
Methyl methacrylate
Disadvantages: PMMA surface hardness is not high, easy to rub hair, anti impact performance is low, the forming flow performance is poor, etc.
Super Transparent PMMA material is mainly used for protecting screen of mobile phone, the products divided into hardening coating, no hardening coating two kinds. Its characteristics are excellent light transmittance, no impurities, electrostatic protective film, surface hardening thickness hardness can reach 5-6h above. At present, the special recommendation for hardening PMMA material, internally called the "plate.
PC lens: was the first to be used for military and industrial door (such as aircraft transparent warehouse, safety mask), the material has excellent anti impact force of the 1990s, due to the development of science and technology, optical grade PC material applied for PC materials for advanced optical lens.0.5CM block 20 meters away from the pistol shooting, general PC lens with a hammer is not easy to smash.

POM: poly formaldehyde
For milky white opaque crystalline linear polymer.
Good comprehensive performance, fatigue resistance is thermoplastic plastics best and room temperature mechanical properties excellent. Abrasion resistance, small friction coefficient, good dimensional stability, surface gloss, creep resistance, resistance to distortion, the repeated impact resistance resistance to carrier recovery is good.
But the molding shrinkage rate is big, but the thermal stability is poor, easy to burn, in the atmosphere, the exposure is easy to aging.
Suitable for the production of wear-resistant parts, transmission parts, as well as chemical engineering, instrumentation and other parts

PP: polypropylene
characteristic：
Non toxic, tasteless, small, strength and stiffness, hardness and heat resistance are better than low pressure polyethylene, can be used at about 100 degrees,
But at low temperatures become brittle, not wear-resistant, easy to aging.
Suitable for the production of general machinery parts, corrosion resistant parts and insulation parts. Common acid, alkali and organic solvent on it has little or no effect, can be used for utensils.
PE is polyethylene.
Polyethylene no odor, non-toxic, it feels like wax, has excellent resistance to low temperature performance (minimum temperature can reach 70 ~ 100 DEG C), good chemical stability, ability of most acid-base erosion (impatience with the oxidizing properties of acid), room temperature insoluble in common solvents, low water absorption, electrical insulation performance is excellent;
But PE is very sensitive to environmental stress (chemical and mechanical action), and its heat resistance is poor.
PE is widely used, and divided into high density, low density and linear PE, daily use most is made of all kinds of plastic film and sheeting
PPO polystyrene ether
1, for white particles with good comprehensive performance, can be used in 120 degrees of steam, good electrical insulation, water absorption is small, but there is a tendency to stress cracking.
2, there are outstanding electrical insulation and water resistance, good dimensional stability, and its dielectric properties in the first place.
3, MPPO for PPO and HIPS blend of modified materials, the current market materials are such materials.
4, there is a high heat resistance, glass temperature of 211 degrees, melting point 268 degrees, heating to 330 degrees have decomposition tendency, PPO content of the higher the better the heat resistance, thermal deformation temperature can reach 190 degrees.
5, good flame retardant, with the self - interest, mixed with HIPS after the medium - flammable.
Disadvantages:
The mobility is poor, is similar to the Newton fluid, the viscosity is more sensitive to the temperature, the thickness of the products is generally more than 0.8 mm.
1, suitable for the production of heat-resistant parts, insulation parts, wear resistant parts, transmission parts, medical and electronic parts.
2, can be used as a high temperature gear, wind blades, valves and other parts, can be used to replace the use of stainless steel.

Polyvinyl chloride PVC
Color is yellowish translucent, shiny. Transparency is better than polyethylene, polystyrene, polystyrene, with different dosage of additives, is divided into soft and hard PVC, soft - ware soft and tough, viscous feel. The hardness of the hard - ware higher than low density polyethylene, and is lower than that of PP and albinism in inflection point will appear.
Common products: plate, pipe, shoe soles, toys, doors and windows, wire skin, stationery, etc.
TPE thermoplastic elastomer
Transparent series has a variety of soft hardness, can be directly processed by the injection molding. Its transparent appearance, smooth surface, soft touch and non-toxic characteristics make it become an excellent transparent material.
