Product description:

PMMA/ABS alloy has the characteristics of ultra-high gloss, high surface hardness, good scratch resistance, excellent weather resistance, etc., so as to achieve the purpose of spray coating-free, the product is environmentally friendly, and the harmony between man and nature is realized. Taking into account the actual needs of customers, Kumho-sunny's high-quality HAM series has better fluidity and a more beautiful surface, of which, the HAM Black series has unparalleled blackness, realizing the perfect combination of function and aesthetics. The products are widely used in the shells and front decorative frames of household appliances such as large computer monitors, LCD TVs, and speakers. ABS has excellent comprehensive performance and is widely used in automobiles, home appliances, office supplies, toys, etc. However, the characteristics of low surface hardness, poor weather resistance and opacity limit the widespread use of ABS in some fields. For example, the concept of environmental protection design is becoming more and more popular, and some products with higher requirements on appearance, such as high-end washing machine panels and LCD TV casings, have higher requirements on the scratch resistance of the base material because the spraying process is omitted. Pencil hardness is usually required to be above the F level, and a single ABS resin is usually not competent. PMMA is a brittle material, and even the impact-modified commercial PMMA has only 3-5KJ/m² notched impact strength, which is difficult to meet the toughness requirements of most molded products. Blending modification is one of the main ways to improve material properties, just as PC/ABS blends can be widely used. PMMA/ABS has the comprehensive properties of scratch resistance, light resistance, high gloss, impact improvement and easy processing, and can obtain transparency through reasonable design, and its dyed products are favored because of their unique visual effects. As early as 2004, Shanghai Kumho-sunny cooperated with several domestic home appliance suppliers to develop scratch-resistant, spray coating-free high-gloss PMMA/ABS materials, and designed transparent, ultra-high flow and other high-performance PMMA/ABS series products, which were successful used in electronic and electrical housings and panel materials, etc. With the design of large-size, thin-walled and light-weight LCD products, PMMA/ABS alloy has gradually demonstrated the incomparable advantages of traditional high-gloss ABS and PC/ABS. Under the market orientation of pursuing aesthetics, PMMA/ABS has obtained the best opportunity for promotion and application.
