Shanghai Daoqin Plastics Co., Ltd.

你 can and 关闭洗发 water bottle cover/cap 子一百次而不会 loss bad it, or 者你 孩子扔掉 and toys it still 然不会受 to loss bad. this is is this product is elastic property 极佳 材 material —— polypropylene (PP) plastics made formed.
PP plastics tool has good resistant use property and excellent impact resistant property, let it can various external impact. this is is what it used for manufacturing day use product use electrical appliances, in automotive industry, toys, use product and plastics pallet, used for textile product, 实验室 and medical equipment manufacturing.

1. what is polypropylene (PP) plastics （pp）?

polypropylene (PP) is thermoplastic property plastics 吗? 没错, polypropylene (PP) is PP（ chemical is (C3H6)n） is propylene polymerization formed thermoplastic property plastics. polypropylene (PP) molecular weight is 1,000,000g/mol, PP density is 0.895至0.93 g/cm3.

this type of plastics 于1951 year polymerization, in short time inner, material in production in 流行起. 如今, polypropylene (PP) plastics is world upper output/production volume most high product 之一. full 球PP polypropylene (PP) market expected to 2021 year will to 7000 10,000 tons, expected future 10 year tool has growth force.

polypropylene (PP) plastics is types Common material

this type of combined formed resin tool has many color hot physical properties. polypropylene (PP) features 包括不 transparent property, tough property, semi rigid property, formed property and good impact resistant property, heat resistant property and chemical resistance. PP polypropylene (PP) has types main/primary type type: homopolymer and copolymer. types type type suitable for pipeline, packaging, textile product, electrical application and medical equipment. types non combined production soft and hard plastics, toys, 橡胶轮胎, insulation material, pipeline, electronics, product and other.

2. polypropylene (PP) material features

2.1 polypropylene (PP) tensile strength

polypropylene (PP) plastics tool has high tensile strength, is 4.800 psi. therefore, this type of thermoplastic property plastics tube/pipe weight light, still can versus large negative 载, let it can resistant impact. this features make its formed is packaging materials.

2.2 polypropylene (PP) flexural strength

polypropylene (PP) flexural strength is 33MPa. this is PP出现塑 property deformation 之点. in to this 一点之 front, polypropylene (PP) is has elastic property. if add force in scope/range inner, material will to its long degree.

2.3 polypropylene (PP) chemical versus property

and “常规” polyethylene (PE) plastics versus ratio, polypropylene (PP) tool has color chemical resistance. many chemical product and it reaction, therefore PP is requirements resistant multiple acid, alkali and has machine solvent agent application （例如 plastics pallet and chemical product container ） 绝佳 selection.

its chemical resistance make its non combined used for agent, product and use product. however, polypropylene (PP) plastics and odor agent, chlorine and oxidation property acid reaction very 差.

2.4 polypropylene (PP) for food safety 吗?

PP plastics food container

polypropylene (PP) for food safety 吗? is has. it is FDA certification plastics, can safety used for food. it not only can pressure, weight light resistant use, but also also tool has relatively high temperature degree, can in micro and machine in use. therefore, use polypropylene (PP) for food safety water 平.

2.5 polypropylene (PP) heat resistant property

polypropylene (PP) temperature degree scope/range versus high. it can in 180°F (82.2°C) temperature degree lower 运行. it combined make used for hot ring lower conditions, and can can effect/influence material quality. however, its in temperature degree made inner use is combined ring in large more application. outer made as application is 一 例子.

if polypropylene (PP) temperature degree scope/range large 于 180°F, material method use, to to 327°F (163.8°C) temperature degree 才发生熔化.

2.6 polypropylene (PP) UV resistant property

polypropylene (PP) can UV resistant 吗? is, in this 情况你不 can versus this type of plastics. it can 承受290-300, 330 and 370 nm（ nano ）波 long outer 线. this is PP light most large value. 接触紫 outer 线会导致材 material degradation.

therefore, although polypropylene (PP) plastics tool has excellent machine strong/high degree and chemical resistance, most good need will it cationic light lower. due to in material upper coating coating 并不容 easy, therefore most good solutions is let it full cationic light.

3. PP engineering plastics composite/compounding material introduction

PP engineering plastics composite/compounding material is 由PP plastics pellets and flame retardant additives, conductive 炭黑, slip material, glass fiber / micro and other specialty reinforcement material blending formed, according to product features requirements, in most product in, manufacturing will selection need add strong/high material.

PP tool has many color features

therefore, PP engineering plastics composite/compounding material remove tool has 传统PP plastics basic features outer, also tool has combined formed product add features. PP composite/compounding material made formed formed product, let enterprise has more simple, more time production process/workflow, from improve/increase production efficiency.

lower table/sheet 列出六 types PP engineering plastics combined material and its application:

summary

polypropylene (PP) plastics is types especially suitable for industry 理想材 material. due to polypropylene (PP) strong/high degree, rigid degree, high melting point and chemical resistance, can in 任何 方见 to it application, packaging, toys, furniture, fiber and material, automotive parts and medical and other industrial application.
