ABS is a copolymer of Acrylonitrile, Butadiene, and Styrene, Its heat-resistance and solvent-resistance are better than HIPS. Besides, it has glass. Due to the stronger Cyantic polAcrylonitrile,themutual action of the PS molecule chain is streng then up. Therefore, the impact strength, the tensile strength and the surface hardness of ABS are better than HIPS.
Generally, the higher percentage of Acrylonitrile, the better the heat-resistance, rigidity and solvent-resistance, however, the worse the flow character; the base color of the plastic is a little yellow, but while injection mold, its mechanical and size stability are very good. Due to the above advantages, ABS resin becomes an excellent engineering plastic.
The POLYLAC® ABS resin of Chi Mei is the most diversified copolymer of Acrylonitrile, Butadiene, and Styrene in the market. Our unique technique enables ABS Resin has its special match and assembly on strength, stability, and process ability. The quality, color dyeing and appearance of POLYLAC® of Chi Mei have won the trust from the customers.
POLYLAC® has been widely accepted and is used in business machinery, electronic parts, communication apparatus, PC, electric appliance, auto parts, bathroom ware, suitcase, faucet and other household items. POLYLAC® covers all kinds of specification in the market, and it has passed the UL and C-UL approval. There are general-purpose grade, high-flow grade, extrusion grade, flame-retardant grade, high-heat grade and transparent grade etc., specification, which may be instantly supplied. In addition, it also coordinates with new purpose to blossom out new grade so as to develop new market.

SAN RESINDue to the poor chemical-resistue of GPPS, we added Acrylonitrile in Styrene to copolymerize the SAN resin, and is also called AS resin. SAN resin not only retains the transparency but also improves the chemical resistance and surface hardness. The natural appearance of SAN pellet is glossy and yellowish.
KIBISAN® is our trade name of AS resin which is a copolymer of Acrylonitrile and Styrene. It was manufactured by our continuous process. Meanwhile, SAN resin has the ggod transparency, high gloss, excellent chemical-resistance property, the high rigidity, the dimension stability and the outstanding high-heat character.
KIBISAN® resin is the best choice for cosmetics case, lighter, food container, battery shell and cleaner vessel. In fact, KIBISAN® is widely used in hundreds of consuming products all over the world. The products include all kinds of level, such as: high-heat class and transparency class commodities. In addition, KIBISAN® AS resin also has passed the UL and C-UL approval.
Currently, the major AS products are: PN-107,PN-117, PN-117C, PN-127, and PN-127H, etc., five kinds products of SAN.

PS RESINThrough heating up the styrene monomer, we can obtain solid polymer which is called General Purpose Polystyrene resin and also called hard resin. Generally speaking, ¨General Purpose Grade" Polystyrene resin has the advantages such as glossy, transparent, and cheap ... etc.
But to point at its disadvantages such as britteness brittle, and the poor chemical endurance...etc, it can sompound with other monomer to improve the quality and develop different kinds of products, such as: High Impact Polystyrene (HIPS), Acrylonitrile-Styrene Copolymer: AS resin, Acrylonitrile-Butadiene-Styrene Copolymer: ABS resin, etc., resins.

ACRYLIC RESINChi Mei ACRYREX® PMMA resin is a mature product that Chi Mei Corporation has accumulated more than 30 years of acrylic sheet manufacturing experience, introduced in US continual process, and used methyl methacrylate (MMA) as major raw material to develop successfully. It has excellent weather-resist and heat-resist character, and excellent transparency and gloss. Besides, it has stable physical, chemical, optical, and electical,etc., characters. It may be widely applied on electronic panel, mechanical parts, watch and clock shell, motorcycle and automobile indicator, tele communication material, insulation parts and sun glasses, etc.

TPEChi Mei thermal plastic elastomer is a copolymer of styrene, and bitadiene. its linear and radical molecular has made it the characteristic of general rubber. Such as elasticity, adn physial charater but without vulcanizatiun. And its middle section is rubber phase, which contributes excellent elasticing, flow ability during processing, cold-resistane and can be injected like thermal-plastics. It is widely appied on sole,toys,asphale modifier instrument handle, and adhesives.

Q RESINQ resin is the transparent coplymer, which copolymerized by Styrene and Butadiene, such material has the following excellent characters: high transparency, high capability, high surface gloss and rigidity, high flexibility, ease to dye/printing processing. It can be compound with GPPS in proper amount; lower the densing can reduce the cost. It meets the requirement of FDA (21 CFR177, 1640). It can be used in regular home appliance, cloth hanger, toy, and packing material.
Currently, the major products are: PB-5903, PB-5906,PB-5910 and PB-5925 etc., four kinds.

ACRYSTEX® MS resin is a transparent copolymer that the major raw materials are methyl methacrylate (MMA) and styrene(SM). It has excellent transparency, optical property, weather-resist, easy to process, ting residual stress, lower water absorption etc. In addition,customer can save more cost due to its specific gravity is lower than PMMA.

ASA RESINASA is a copolymer of Acrylonitrile, Styrene, and Acrylate rubber. Technically, ASA maintains the characteristics of ABS and by switching the rubber to Acrylate rubber, ASA improves the weatherability of ABS and make a great leap to extend the applications of ABS, especially in outdoor purposes. With over 30 year experiences in developing ABS, KIBILAC®ASA inherits the good qualities and properties of POLYLAC® ABS. Weather endurance, long-term stability, color stability, and good compatibility with PC/PVC lead KIBILAC®ASA to wider usability and higher value, including scooter and automotive parts, constructions, outdoor sporting goods, garden parts, satellite dishes, E/E parts, bathroom appliances, etc. In addition, KIBILAC® ASA has the advantages of cost-saving and environment-protecting due to painting and electroplating are unnecessary for the end parts. Currently, KIBILAC® offers 3 grades, PW-957, PW-978B, and PW-997S.
