产品描述
High glossy compound PP SI51C and SH52C are improved heat resistant PP grades. These products have the high heat-resistance required for use in electric heating equipment parts, as well as superior surface gloss and scratch-resistance.
These are Korea's best high heat-resistant, high glossy compound PP products, They are designed for the exterior housing s of household appliances which require an elegant appearance, such as rice cookers, toasters, irons, jars, pots, and bread makers.
Characteristics
SI51C and SH52C employ high crystalline PP (HIPP: High Isotactic PP) as the base resin which contributes to heat-resistance, rigidity and scratchresistance, all of which are superior to those found in common PP.
These grades of PP also feature excellent the mechanical-property balance required for use in electric heating equipment. Our SI51C & SH52C has superior thermal durability reflected in its RTI Relative Thermal Index) certification value of temperature, 120℃, based on the regulation of UL746B.
Applications
▶ Rectangular rice cooker housings bodies, bases, and covers
▶ Bread-makers, irons, and hot pots
▶ Electronic products requiring high heat-resistance, high glossiness, and clear finish
