Calcium carbonate masterbatch from HDPE base resin - The best material for plasticsby Tran Hoa Marketing
HDPE is an important component of the plastic industry. They have an important role in producing plastic items, nylon bags, tools, plastic pallets, plastic containers, corrugated plastic, solid plastic containers, empty plastic containers, plastic waste bins .... So a significant part of this material is calcium carbonate masterbatch.
What is HDPE? What are the roles of calcium carbonate masterbatch in the production of HDPE?
HDPE stands for Hight Density Poly Ethylene, which is one of many polymers derived from polyethylene. Polymerized from PolyEthylene (high density) in relatively low pressure and catalyst systems are widely used to ethylene polymerization is Xigle-Naptha (TiCl4 + Al (C2H5) 3). This is one of the most common materials used to produce plastic products such as water pipes, plastic cans, plastic cups, plastic bags, ... and many other products to serve the demands of poeople. Calcium carbonate masterbatch is the most important additive of this compound. PolyEthylene molecules are the basic materials, along with other catalysts and additives including taical that make up this material.
Some properties of HDPE materials:
Non-hygroscopic, water absorption <0.02%
Low softening point (90oC), very easy to process.
Good chemical resistance, good electrical insulation.
Tensile force114 ÷ 150kg / cm2, elongation 400 ÷ 600%, Heat Tg: -80 degrees C
Bending force 60 kg / cm2, shore hardness (ASTM-D2240): 30 ÷ 35
Brinel hardness 1.8 ÷ 2.5kg / cm2, MI flow index: 0.1 ÷ 60gr / 10m.
Poor adhesion, easy to flow, odorless, tasteless, non-toxic.
The advantages of HDPE and calcium carbonate masterbatch in plastic pipe production
Plastic pipe possesses valuable properties when compared with other calcium carbonate masterbatch pipe:
- Extremely durable HDPE pipes, withstand very well in the environment of liquids as well as common solutions on roads, soil, water supply and drainage. It does not rust and is not affected by solutions such as salts, acids and alkalis, even in acid rainwater will not affect these HDPE pipes. The main reason is the HDPE material containing calcium carbonate masterbatch and other additives to enhance the properties.
- Perfect endurance for sunlight and environmental temperature of HDPE pipe is very good, the product is not mechanized or aging when HDPE pipe is constructed for a long time under strong impact of UV rays.
- At extremely low temperatures below –40 ° C, HDPE pipes will retain the pressure and impact much better than other plastic pipes. HDPE pipes also have excellent fire resistance. When affected by the fire, HDPE plastic pipe is hard to catch fire, the product only softens and has a little deformation. The temperature of HDPE pipe is extremely high at about 325C
- HDPE pipes have very large malleable properties and can withstand a lot of deformation under high load types. This is also a common feature in conventional plastics, apart thanks to calcium carbonate masterbatch that make the product more flexible.
