PP is a semi-crystalline material. It is harder and has a higher melting point than PE. Since the PP temperature of the homopolymer type is very brittle when it is higher than 0 \u00b0 C, many commercial PP materials<\/a><\/strong> are random copolymers of 1 to 4% ethylene or a clamp copolymer of a higher ratio of ethylene. The copolymer type PP material has a low heat distortion temperature (100 \u00b0 C), low transparency, low gloss, low rigidity, but has a stronger impact strength. <\/p>

The strength of PP increases as the ethylene content increases. The Vicat softening temperature of PP is 150 \u00b0C. Due to the high degree of crystallinity, this material has excellent surface stiffness and scratch resistance. There is no environmental stress cracking problem in PP. The PP is usually modified by adding glass fibers, metal additives or thermoplastic rubber.<\/p>

La tasa de flujo de PP tiene un MFR que var\u00eda de 1 a 40. Los materiales de PP con bajo MFR tienen mejor resistencia al impacto pero menor elongaci\u00f3n. Para materiales del mismo MFR, la resistencia del tipo copol\u00edmero es mayor que la del tipo homopol\u00edmero. \"M\u00e1quina<\/p>

Due to crystallization, the shrinkage rate of PP is quite high, generally 1.8 to 2.5%. And the direction uniformity of shrinkage is much better than materials such as PE-HD. <\/p>

The addition of 30% glass additive can reduce the shrinkage to 0.7%. Both the homopolymer type and the copolymer type PP materials have excellent moisture absorption resistance, acid and alkali corrosion resistance, and solubility resistance. However, it is not resistant to aromatic hydrocarbons (such as benzene) solvents, hydrogen chloride (carbon tetrachloride) solvents, and the like. <\/p>

PP does not have oxidation resistance at high temperatures like PE, and it is harmful to the human body.<\/p>

Los vasos desechables utilizados en la vida diaria est\u00e1n generalmente hechos de pl\u00e1stico pc y pp.<\/h3>

El PC es un material de ingenier\u00eda amorfo con una excepcional resistencia al impacto, estabilidad t\u00e9rmica, brillo, inhibici\u00f3n bacteriana, propiedades retardantes de llama y resistencia a las manchas. La brecha del PC<\/p>

La resistencia es muy alta y la tasa de contracci\u00f3n es muy baja, generalmente del 0.1% al 0.2%. El PC tiene buenas propiedades mec\u00e1nicas, pero las caracter\u00edsticas de flujo son malas, por lo que esto<\/p>

El proceso de moldeo por inyecci\u00f3n de materiales es dif\u00edcil. Al elegir qu\u00e9 material de PC de calidad utilizar, debe basarse en las expectativas finales del producto. Si la pieza de pl\u00e1stico requiere alta resistencia al impacto, entonces use un flujo bajo.<\/p>

Material PC cin\u00e9tico; por el contrario, se pueden utilizar materiales PC de alta tasa de flujo para optimizar el proceso de moldeo por inyecci\u00f3n.<\/p>
