PP homopolymer granule Hanwha PP HJ730 polypropylene price per kg for coffeepot and electric kettle pp polypropylene

Introduction Edit broadcast Polypropylene, a kind of plastic, is a linear polymer with high density, no side chain and high
crystallinity, and has excellent comprehensive properties. Common products: basin, barrel, furniture, film, woven bag, bottle cap,
car bumper, etc. PP plastic, chemical name: polypropylene English name: Polypropylene (abbreviated as pp) Specific gravity:
0.9-0.91g/cm3 Molding shrinkage: 1.0-2.5% Molding temperature: 160-220 ℃ PP is a crystalline polymer, and its comprehensive
performance is better than PE material. PP products have light weight, good toughness and good chemical resistance. Disadvantages
of PP: low dimensional accuracy, insufficient rigidity, poor weather resistance, post-shrinkage, easy aging, embrittlement and
deformation after demoulding. In daily life, the commonly used fresh-keeping box is made of PP material. Heat resistance editing
and broadcasting PP polyester is a kind of non-crystal, its melting point should be above 220, and its thermal deformation
temperature should be about 121 degrees. However, since it is a macromolecular polymer, the higher the temperature, the greater
the possibility of small analytical oligomers precipitated, and most of these substances are not conducive to human health. And
according to the customer's use, the boiling water is generally 100 degrees, so the general plastic cup will not be marked with
more than 100 degrees. There is non-toxic editing and broadcasting If you want to know whether pp material is toxic, let's first
have an accurate understanding of the essence of pp material. The so-called pp material, also known as polypropylene in our daily
life, is a white translucent linear polymer without side chain and high density. It has good oil resistance and weak acid and
alkali resistance. Its comprehensive performance is good, and it is often used for household, barrel, basin, bottle cap and other
things. In the interior of pp material, high-purity propylene is the main material, which includes a small amount of ethylene
copolymer. After drying, mixing, extrusion, granulation, screening and homogenization, the polypropylene particles are cylindrical
particles, which are very smooth and clean, free of any mechanical impurities, and have good mechanical properties and heat
resistance, It is non-toxic to use in the temperature range from minus 30 ℃ to 140 ℃
