Ethylene vinyl acetate copolymer, called EVA. Ethylene vinyl acetate (VA) content in 5%-40%, and polyethylene (PE) compared to EVA due to the molecular chain of the vinyl acetate monomer, thereby reducing the high crystallinity, improved toughness, impact resistance, filler compatibility and heat sealing perbbbbance, is widely used in foam material, functional films, packaging mold, hot melt adhesive, wire and cable and toys and other fields.

PA612 is mainly used for bristles for toothbrushes and other advanced industries, can also be used for the production of precision machinery parts and electrical wire and cable coating coating, oil pipe, oil resistant conveyor belts, ropes, bearing, liner, the military can be used for gunstocks, helmet and military cables.

Injection molding process

Drying treatment:

If the material is sealed before processing, it is not necessary to dry. However, if the storage container is opened, it is recommended to dry at 85 C hot air. If the humidity is greater than 0.2%, it is necessary to vacuum drying at 105 and 12 hours.

Mold humidity:

Recommendation 80. C mold temperature affects the crystallinity, and the crystallinity will affect the physical properties. For thin wall plastic parts, if you use less than 40 degrees, the mold temperature, plastic parts of the crystallinity changes with time, in order to maintain the geometric stability of plastic parts, the need for annealing.

Injection pressure:

It's usually in 750~1250bar, depending on the material and the design of the new product.

PBT Because of its high melting point and crystallinity, the water absorption and thermal expansion coefficient are also very low, so it has excellent dimensional stability. In addition, it has excellent electrical insulation, the electrical property caused by the hygroscopic property changes very little, and the insulation voltage is very high.

In the aggregation structure of PBT, there are crystalline and amorphous regions, so it can be easily modified by adding other substances and endow them with various functions. The existing flammable grade, high speed molding grade and high impact resistance grade endowed various kinds of grades.

Connectors, small switches, capacitor housing and other electronic components, OA mechanical keyboard and VTR, bbbephone and other functional mechanical components, vehicle electronic components, car door handles and other automotive components. Also, medical machinery, building materials, precision machinery, etc. are widely used in many of our daily articles and utensils.

The property is high crystalline plastic plastic, the melting point is 220~230 C, and the crystallization rate is faster than that of PET.

Advantages of 1, mechanical properties, tensile strength and tensile modulus and nylon resemble

2. Small friction coefficient is self moistening

PC/ABS In order to meet this demand, kumhosunny and Yanfeng Wei Shitong successfully developed a new generation of PC/ABS ultra low gloss materials HAC8250Z and HAC8260Z. The material not only satisfies the low gloss requirements of the parts below the inner waist line of the car, but also balances the fluidity and heat resistance.

A new generation of ultra low gloss PC/ABS due to its low gloss outstanding has been successfully applied to the Shanghai Volkswagen Skoda crystal sharp steering wheel cover, the surface gloss of parts at 60 degrees under the test value is 4.2 (K31, 1.5 degrees of skin color, 9B9), to meet the automotive interior under the waist gloss requirements. At the same time, kumhosunny also together with customers to develop PC/ABS HAC8260Z dashboard matte material, the material not only to replace the original steel dashboard framework, and is directly exposed dashboard without nakedness materials currently used in paint, SAIC Iveco Hongyan models.

We are convinced that the new generation of PC/ABS ultra low gloss materials will continue to be applied with the gradual implementation of the ELV regulations.
