PP flame retardant level Introduction:

PP Polypropylene is a non-toxic, odorless, odorless milky white crystalline polymer with a density of only 0. 90 - "0.9g / cm 3 , which is one of the lightest varieties in all plastics. Stable, water absorption in water is only 0. 01%, molecular weight of about 81,000 to 150,000. Good shape, but the shrinkage of large (1% to 2.5%). Thick-walled products easy to depression, for some dimensional accuracy High parts, it is difficult to meet the requirements, the product surface gloss is good.

Non-toxic, tasteless, low density, strength, stiffness, hardness and heat resistance are better than low-pressure polyethylene, can be used at about 100 ℃. Has good dielectric properties and high frequency insulation and is not affected by humidity, but low temperature brittle, not wear, easy aging. Suitable for the production of general mechanical parts, corrosion-resistant parts and insulation parts. Common acid, alkali and other organic solvents to it almost does not work, can be used for utensils.

Polypropylene has many excellent properties:

1, the relative density of small, only 0.89-0.91, is one of the lightest varieties of plastic.

2, good mechanical properties, in addition to impact resistance, the other mechanical properties are better than polyethylene, forming processing performance.

3, with a high heat resistance, continuous use of up to 110-120 ℃ temperature.

4, chemical performance is good, almost no water, and most of the chemicals do not respond.

5, texture pure, non-toxic.

6, good electrical insulation.

7, polypropylene products, transparency than high-density polyethylene products, transparency is good.

It has a lot of advantages but also shortcomings:

1, poor cold resistance products, low temperature impact strength is low.

2, the use of products in the light, heat and oxygen in the role of aging.

3, the color is not good.

4, easy to burn.

5, toughness is not good, high electrostatic, dyeing, printing and poor adhesion.

Through the modification can change the shortcomings of PP raw materials: Branch yuan Plastic Co., Ltd. plastic business scope includes: flame retardant PP enhanced PP cold PP toughening PP high impact PP and LFT long fiber PP etc .. welcome to consult the discussion All materials are used internationally renowned brands as the base material; can be detected by the relevant national testing unit certification: free of charge to provide SGS; UL environmental protection and other test reports and material properties table ...
