Sell LDPE Virgin Granules

详情

Low-density polyethylene（LDPE）is a synthetic resin using a high pressure process via free radical polymerization of ethylene and is therefore also called “high-pressure polyethylene”. Since its molecular chain has many long and short branches, LDPE is less crystalline than high-density polyethylene (HDPE) and its density is lower. It features light, flexible, good freezing resistance and impact resistance. LDPE is chemically stable. It has good resistance to acids (except strongly oxidizing acids), alkali, salt, excellent electrical insulation properties. Its vapor penetration rate is low. LDPE has high fluidity and good processability. It is suitable for being used in all types of thermoplastic processing processes, such as injection molding, extrusion molding, blow molding, rotomolding, coating, foaming, thermoforming, hot-jet welding and thermal welding. Our products are classified into Film Grade, Injection Molding Grade, Coating Grade, Artificial Flower Grade, Wire & Cable Grade, Ethylene Vinyl Acetate(EVA), etc

Application:

LDPE is principally used for making films. It is widely used in the production of agricultural film (mulching film and shed film), packaging film (for use in packing candies, vegetables and frozen food), blown film for packaging liquid (for use in packaging milk, soy sauce, juice, bean curds and soy milk), heavy-duty packaging bags, shrinkage packaging film, elastic film, lining film, building use film, general-purpose industrial packaging film and food bags. LDPE is also widely used in the production of wire & cable insulation sheath. Cross-linked LDPE is the main material used in the insulation layer of high-voltage cables. LDPE is also used in the production of injection-molded products (such as artificial flowers, medical instruments, medicine and food packaging material) and extrusion-molded tubes, plates, wire & cable coatings and profiled plastic products. LDPE is also used for making blow-molded hollow products such as containers for holding food, medicine, cosmetics and chemical products, and tanks.

Yan De LDPE prodcuts cover the following main categories:

 

Film Grade:
LDPE film grade can be categorized into several groups–general purpose film, highly transparent film, heavy-duty film, shrinkage film and casting film. These products have excellent physical and mechanical performence, good chemical stability and electric insulation, low permeability to vapor, and excellent processability. Films produced using these resins has excellent transparence and aging resistance.          

Injection Molding Grade:
LDPE Injection-molding grade can be used in the production of polyethylene foaming material, powdered coating and injection-molded products. The resin has a molecular structure with branching. It has high melt strength, good mechanical behavior, heat endurance and chemical corrosion resistance and excellent processability. Products made from this resin have many advantages such as short shaping cycle, small shrinkage rate and stable dimensions.

Coating Grade:

LDPE coating grade can be rolled flat with a low permeability to vapor. It is characterized by good thermal sealing property, broad molecular weight distribution, high degree of branching, good adhesive bonding when used as coating, and is suitable for high-speed extrusion coating.

Artificial Flower Grade:

LDPE artificial flower grade has the high melt flow rate, it leads to excellent flowability and processability and anti-chemical corrosion.

Wire & Cable Grade:

LDPE wire & cable grade has a density and melt flow ratevery suitable for the material being used as cable base material.This is achieved by controlling its molecular structure. The resin has high dielectric strength and volume resistivity, low dielectric loss tangent and dielectric constant.

Ethylene Vinyl Acetate(EVA):

EVA is a thermoplastic copolymer manufactured through the free radical polymerization of ethylene and vinyl acetate in the presence of initiating agents using the high-pressure bulk polymerization process. EVA's properties vary dramatically from one product to another depending on the content of vinyl acetate in the macromolecule. EVAs with different properties are used for different purposes.
