KIBITON® is a copolymer of styrene and butadiene. It shows some of the characteristics of thermoset rubber such as elasticity and low temperature performance with the advantages of a thermoplastic such as melt processibility. 

Its segmented and radial molecular structure allows it to have the same flexible and physical properties of general rubber without the vulcanization process. Its middle segment is similar to rubber and has excellent elastic restoring force, processing flowability, weather resistance, and can be injection molded similar to that of thermoplastics. It can be widely applied for shoe soles, toys, asphalt modifications, mechanical products, plastic modification agents, and adhesive agents.

Kibiton

This solid polymer is formed by heat polymerization of styrene monomer. This product is referred to as the general purpose polystyrene, also known as hard plastic. Generally speaking,  general purpose polystyrene has the advantages of being bright, lightweight, transparent, low cost, etc. In addition, if rubber is added and mixed during the polystyrene production process, impact resistant and non-transparent polystyrene commonly known as the high impact polystyrene (HIPS) can be developed.

Polyrex

WONDERLITE® is a polycarbonate resin polymerized using the double hydroxy compounds of BPA (bisphenol-A) and the diphenylcarbonates of carbonate compounds with the transesterification (melting) method. Absolutely no phosgene and chlorinated solvents such as dichloromethane were used during the manufacturing process. Our polycarbonate resins are FDA and UL certified.

WONDERLITE® Polycarbonate Resin has excellent transparency, high heat resistance, ultra high impact resistance, dimensional stability, etc., making it suitable for a wide range of applications. All 3C products, electrical and electronic products, precision machinery, instrument products, automotive parts, sporting goods, recreational goods, sanitary hygiene products, CD/DVD related products, etc.

Wonderlite

ASA is a copolymerization of styrene, acrylonitrile, and acrylic rubber. Technically, ASA not only maintained the main characteristics of the ABS, it also combines the weather resistance advantage of acrylic to extend the product application for outdoor purposes.

Following 30 years of experiences in manufacturing ABS, KIBILAC® ASA has inherited the good qualities and characteristics of Chimei’s POLYLAC® ABS. The characteristics of weather resistance durability, color stability, and good PC/PVC capability have allowed KIBILAC® ASA to become a broader and higher value resin that can be applied in automotive parts, construction parts, outdoor sporting goods, gardening parts, outdoor antenna parts, electronic and electrical products, toiletries, etc.

In addition, KIBILAC®ASA also reduces the secondary coating and electroplating processing costs, allowing its products to have cost reducing and environmental friendly features. Presently, primary ASA product specifications are PW-957, PW-978B, and PW-997S.

Kibilac

ACRYREX is a plastic material successfully manufactured by the Chi Mei Corporation using methyl methacrylate (MMA) as the main raw material after three decades of acrylic sheet manufacturing experiences and the introduction of continuous process technology from the United States. It has good cleanliness, high transparency and gloss, as well as stable physical, chemical, optical, and electrical properties. Can be widely used in the application of electronic panels, mechanical parts, surfaces of watches and clocks, vehicle lights, telecommunication equipment, insulation parts, and sunglasses.

Acryrex

KIBISAN® SAN is a copolymerization of styrene-acrylonitrile. Acrylonitrile monomer (AN) is added to styrene monomer (SM) to copolymerize SAN, also commonly known as the AS Resin. SAN not only retains the transparency of GPPS, it also has more chemical resistance and slightly increased surface hardness. Under natural conditions, it is a bright yellowish transparent object. The SAN product manufactured by our unique continuous process has good transparency, uniform high gloss, chemical resistance, superior heat resistance, rigidity, and stability.

KIBISAN ® is the best material for cosmetic containers, lighter casings, food processing containers, battery casings, detergent sprayer apparatuses, etc. In fact, KIBISAN® has been applied in the manufacturing of hundreds of consumer products globally, including products of various grades from high heat resistance to transparent products. KIBISAN® has also been UL and CUL certified

Kibisan

The MS Resin ACRYSTEX® of Chimei is a transparent copolymerization primarily composed of methyl methacrylate (MMA) and styrene monomer (SM). Its advantages include excellent transparency, optical properties, low hygroscopicity, good weather resistance, ease of processing, low residual stress for molded products, etc. The proportion of MS Resin is lower compared to that of Acrylic, and the cost is also cheaper.

Acrystex

PC Alloy is a material with excellent balanced properties from PC and ABS. PC provides high heat, high impact, flame retardant and high tensile strength properties, and ABS gives better processing ability, impact strength under low temperature environment and able to be electroplated. The applications range from OA, networking, computer/communication/consumer electronics products to NB and TV industry.
