PET
is divided into fiber-grade polyester chips and non-fiber-grade polyester chips.
Fiber-grade polyester is used to manufacture polyester staple fibers and polyester filaments, and is the raw material for polyester fiber enterprises to process fibers and related products. Polyester is the most productive variety of chemical fibers.
Non-fiber polyester is also used for bottles, films, etc., and is widely used in the packaging industry, electronic appliances, medical and health, construction, automobiles and other fields. Among them, packaging is the largest non-fiber application market for polyester, and it is also the fastest growing PET market. fast field.
PP:
PolypropyleneS is a polymer of propyleneS by addition polymerization.
It is white waxy material, transparent and light in appearance.
Chemical formula is (C3H6) N, density 0.89 ~ 0.91g/cm3, flammable, melting point 189ºC, softening at 155ºC or so, the use of temperature range of -30 ~ 140ºC.
Under 80ºC, it can resist the corrosion of acid, alkali, salt liquid and various organic solvents, and can decompose under the action of high temperature and oxidation.
PolypropyleneS is widely used in the production of clothing, blankets and other fiber products, medical instruments, automobiles, bicycles, parts, pipelines, chemical containers, and also used in food and drug packaging
.
HDPE:
High density Polyethylene (HDPE)
:
is a highly crystalline non-polar thermoplastic resin produced through the copolymerization of ethylene and a small amount of α-olefin monomer. HDPE is synthesized under low pressure and is therefore also called low-pressure polyethylene. HDPE is mainly a linear molecular structure and has little branching. It has a high degree of crystallization and high density. It can withstand high temperatures and has good rigidity and mechanical strength and anti-chemical corrosion.
Properties:
High density polyethylene for non-toxic, tasteless, no smelly white particles, melting point is about 130 ° C, relative density of
0.941 ~ 0.960. It has good heat resistance and cold resistance, chemical stability, but also has high rigidity and toughness, good
mechanical strength. Dielectric properties, environmental stress cracking resistance sex also is good.

Q1: What's your MOQ?
A1: Normally, our MOQ is 1 FCL, but we could apply less quantity if customers have special requirements on quantity, just the price for LCL will be a little higher than FCL.
Q2. How can I get the new price of a product?
A2: Please provide the exact or approximate quantity, packing details, destination port or special requirements, then we could give you the price accordingly.
Q3: How can I get a sample?
A3: We can provide free samples for your test, but samples freight should be paid by your side.
Q4. How do you guarantee the quality?
A4: First of all, our quality control will reduce the quality problem to near zero. When the production is finished, they'll take
samples from every batch of cargo, and send to our lab for inspection. After pass15ed the inspection, then we will arrange the delivery.
Q5: Is this price your real price?
A5:Yes, but the price is floating, i suggest you contact us before you place an order
