UHMWPE is the abbreviation of ultra high molecular weight polyethylene. This is the most excellent quality available for use in harsh working environments and in a variety of applications. Applicability is very good in many highly difficult applications.
UHMWPE is a product that have many advantages that not to many plastics and be used many fileds.
The advantage of UHMWPE as follows:
1. Wear-resistance
The wear resistance of UHMWPE ranks first in plastic, and exceeds that of certain metals.
Material UHMW-pe MC nylon PA-66 PTFE POM HDPE PVC Carbon steel Brass
Mortar wear index 1 4 5 5 6 10 10 7 27
2. Impact resistance
The impact strength of UHMWPE at the top of all engineering plastic.
Material UHMW-PE PA 66 PC ABS PBT
Unit(KJ/m2) 140 9 80 15 5
3. Self-lubrication
UHMWPE has a very low coefficient of friction(0.05-0.11),so that it has a very good self-lubrication.
4. Corrosion resistance
UHMWPE has excellent resistance to chemicals,in addition to the strong oxidizing acid,in a certain temperature and the concentration range of competence of various corrosive medium (acid,alkali,salt) and various organic media.
5. Absorb impact energy
UHMWPE has excellent shock absorption,impact energy absorption value is the highest in all plastic,and it has a excellent effect of the silencer.
6. Low temperature resistance
UHMWPE has excellent low temperature resistance,and can be used as a low temperature component in the nuclear industry because of its still have the ductility at low temperature (-269?).
7. Hygiene and no toxicity
8. Not easy adhesion
UHMWPE surface adsorption force is very weak, its ability to resist adhesion to the plastic is next only to the best PTFE, so the surface of the product and other materials are not easy to stick.
9. Hydrophobic property
UHMWPE water absorption rate is very low, generally less than 0.01%, only 1% of PA6, and therefore do not need to dry before processing.
10. Tensile strength
As the UHMWPE has the necessary structural characteristics of the super tension orientation, so there is no comparable ultra-high tensile strength, its tensile strength up to 3 - 3.5GPa.
HDPE is the abbreviation of High Density Polyethylene and it is an excellent engineering plastic.
HDPE was known by people for a step by step because it has many unique and useful properties. The density of HDPE is 0.94-0.98g/cm3. HDPE have many properties, such as high-wear-resistance,good-chemical resistance, low-temperature resistance, self-lubrication and high-impact resistance, soft and ductile, non-toxic tasteless and safety and healthy.
HDPE is widely used in industry, include the rope, woven bag, fishing nets, water pipes, non load bearing member, bollte.
