? pp材質(zhì)是什么材料
? 聚丙烯，是一種塑料，具有質(zhì)輕、韌性及耐化學(xué)性佳等優(yōu)勢(shì)。
PP又稱聚丙烯，是一種無(wú)色、無(wú)臭、無(wú)毒、半透明固體物質(zhì)，是一種性能優(yōu)良的熱塑性合成樹脂，為無(wú)色半透明的熱塑性輕質(zhì)通用塑料。具有耐化學(xué)性、耐熱性、電絕緣性、高強(qiáng)度機(jī)械性能和良好的高耐磨加工性能等，這使得聚丙烯自問(wèn)世以來(lái)，便迅速在機(jī)械、汽車、電子電器、建筑、紡織、包裝、農(nóng)林漁業(yè)和食品工業(yè)等眾多領(lǐng)域得到廣泛的開發(fā)應(yīng)用，聚丙烯的綜合性能很不錯(cuò)，材質(zhì)無(wú)毒，使用后對(duì)人體無(wú)害。

pp材質(zhì)的優(yōu)點(diǎn)：

1.耐撞，大多數(shù)pp材質(zhì)的耐撞擊能力非常強(qiáng)，物理性能穩(wěn)定。

2.質(zhì)量小，會(huì)比一般的塑料材質(zhì)輕巧。

3.塑形能力較強(qiáng)，可制作不同物體。

4.耐熱性能好，制作過(guò)程中要經(jīng)過(guò)高溫鍛造，使其具有了較好的耐熱性。

5.化學(xué)性能穩(wěn)定，PP材質(zhì)所制作的東西基本不與酸堿物發(fā)生化學(xué)作用，性能穩(wěn)定。

What is the material of PP
Polypropylene is a type of plastic with advantages such as lightweight, toughness, and good chemical resistance.
PP, also known as polypropylene, is a colorless, odorless, non-toxic, and semi transparent solid substance. It is a high-performance thermoplastic synthetic resin and a colorless and semi transparent thermoplastic lightweight universal plastic. Polypropylene has chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties, and excellent wear-resistant processing properties. Since its inception, it has rapidly been widely developed and applied in many fields such as machinery, automobiles, electronic appliances, construction, textiles, packaging, agriculture, forestry, fishery, and food industry. Polypropylene has excellent comprehensive properties, non-toxic materials, and is harmless to the human body after use.

Advantages of PP material:
1. Impact resistance, most PP materials have strong impact resistance and stable physical properties.
2. The quality is small and lighter than ordinary plastic materials.
3. Strong shaping ability, capable of making different objects.
4. Good heat resistance, requiring high-temperature forging during the production process to ensure good heat resistance.
5. Stable chemical properties, PP materials make things that do not react with acids or alkalis, resulting in stable performance.
