PBT/ABS alloy is a kind of engineering plastic with excellent performance, which maintains the good processing fluidity, heat resistance, cold resistance and chemical resistance of PBT, and improves the impact toughness and dimensional stability of PBT. The dimensional stability, impact performance and warpage of PBT/ABS are obviously improved after being reinforced by glass fiber.

Polybutylene terephthalate (PBT) is an engineering plastic with excellent properties, with excellent toughness and fatigue resistance, good heat resistance and weather resistance, good electrical properties and low water absorption. Reinforcement and flame retardant modification can significantly improve its heat resistance, modulus, dimensional stability and flame retardancy, and are widely used in automotive, electrical and electronic industries.

PA/ABS alloy is an amorphous/semi-crystalline system, the addition of ABS improves the water absorption and notch toughness of PA, while the addition of PA improves the chemical resistance, heat resistance and fatigue resistance of ABS. As we all know, PC/ABS is the most widely used and deeply researched ABS alloy, and one of the most important alloy products of ABS. At present, PC/ABS materials are used for automotive interior materials, especially the peripheral products of automotive dashboards. In contrast, PA/ABS alloys bring unparalleled performance and appearance advantages to automotive interior parts with their unique charm. (1) PA/ABS material can bring a soft matte effect on the surface, which is not available in other materials. For automotive interior materials, on the premise of satisfying the basic mechanical properties and thermal properties required by the components, they are generally required to have a matte function to help reduce the driver's visual fatigue, thereby improving driving safety. At present, ordinary materials need to be treated by spraying matte paint or adding matte agents to modify the materials before they can meet the requirements of interiors. Although PC/ABS can reduce gloss by adding a matte agent, there is still the defect of uneven gloss distribution. The unique matte properties of PA/ABS materials can avoid these problems very well. (2) The heat resistance of PA/ABS material is no less than that of PC/ABS material. Especially in the case of low load (1kg), its heat resistance is better than that of PC/ABS material. The Vicat softening temperature of PA/ABS can reach 180℃ (A/50), which is unmatched by PC/ABS materials. (3) The density of the PA/ABS material can also be reduced by as much as 6%, thus effectively reducing the cost. The relative density of PC/ABS materials is relatively high, generally in the range of 1.13-1.15, while the density of PA/ABS is 1.07-1.08, which is commensurate with heat-resistant ABS materials. (4) The product fluidity of PA/ABS is very good, it has better processability than other materials, and the processing window is wider.

Kumho-sunny's MPPE has excellent mechanical properties, heat resistance, low water absorption, good dimensional stability, hydrolysis resistance, high temperature and low creep performance, and is widely used in automotive, electrical and electronic, water pumps and other fields.

Kumho-sunny meltblown PP special material (brand PP-1500) is made of low-odor polypropylene and low-odor initiator as the basic raw materials, and is prepared by chemical degradation method of "directional fracture" combined with advanced processing technology.

HEPS WR105 is a weather-resistant and impact-resistant PS plastic. On account of it does not contain unsaturated double bonds, its weather resistance is much higher than that of ordinary HIPS and ABS plastics. And it has high impact performance, which can reach the equivalent level of ABS. It can replace plastics such as ABS and ASA in certain fields, which is mainly used in fields that require weather resistance and high impact.
