HTH52是一种高结晶聚丙烯,具有优异的机械性能,包括弯曲模量、表面硬度和拉伸强度。它们的使用也会降低产品重量。 Description Made from high crystalline PP, compound PP TI51H, HTB52, HTB72 and HTH52 provide superior mechanical properties, including flexural modulus, surface hardness and tensile strength. Their use will also result in reduced product weight. Lightening of materials: Superior mechanical properties - Development of thin wall product - product weight reduction - Talc 30% grade substitution -reduced specific gravity Primary Applications: Heater cases, body consoles and center pillar-UPR. Due to their high scratch-resistance , they are ideal for use in for auto interior parts. In addition, owing to superior heat-resistant characteristics, these products can effectively be used in high-temperature conditions such as in engines and in air-conditioning system parts. Characteristics Outstanding mechanical properties including flexural modulus and surface hardness Remarkable plasticity due to low-shear stress and shear-viscosity at high shear rates, such as in injection molding Reduced cooling time and improved productivity due to the high crystallization speed unique to high crystalline PP Advantages over existing PP compounds due to significantly higher scratch- and heat resistance. Applications Interior parts for automobiles, body-consoles, pillars, trim and heater cases: Heat-resistance and weatherability. Prevents deformation and discoloration of car parts caused by heat within closed spaces and ultraviolet rays during summer. Anti-static characteristics, Prevent static-electricity, which can affect electronic systems in automobiles. Superior processability and scratch-resistance: Superior processability allows better finishes, while use of high crystalline PP affords excellent scratch and heat resistance; ideal for interior parts and air conditioner components. |
