Product

Application

NDGJ-01

Black Weatherability and Resistance to Electricity Mark HDPE Insulating Compound for Aerial Cables

Applied to less than  10KV aerical cables as insulation which has the requirements of resistance to  electricity mark.

NDPE-22

Black Resistance to  Electricity Mark PE Jacket Compound

Applied to ADSS fiber  cables as jacket which has the requirements of resistance to electricity  mark.

NDPE is a black and resistance to electricity mark PE jacketcompound special for ADSS cables, which based on PE polymer. NDPE has specialadditive. It has very good performance of resistance to electricity mark, andexcellent electrical properties, weatherability, tenacity, abrasive resistanceand excellent resistance to environmental stress crack. Meeting DL/T 788-2001standard.

Processing

The NDPE compound suits to process with extruder which L/D is 25 orabove 25. And it should be dried before using, the temperature is 90.

Q:Do all plastic products taste?
In the life of commonly used plastic polyethylene (used for making plastic wrap, bags, cups, pearl cotton, this is the most secure plastic products, no toxicity); (polyvinyl chloride pipes, packaging bags and other plastic products used in the production of PVC, is not toxic, but is in high temperature or other extreme conditions may release toxic hydrogen chloride);
Q:Can plastic bottles be recycled?
Resistant to 130 degrees high temperature, 5 represents PP polypropylene) microwave oven lunch box made of this material. The transparency of the poor, some lunch box body produced by PP, the lid is to PS PS polystyrene) manufacturing, good transparency, but not heat, so can not be put together with the box of microwave oven; heat cold, plastic bottle manufacturers on behalf of 6 PS PS) which is used for making instant noodle box, foamed lunch box material. But don't put it in the microwave oven and try not to pack hot food with a snack bar
Q:EVA plastic products poisonous?
EVA plastic products are non-toxic.Ethylene vinyl acetate copolymer, referred to as EVA. Ethylene vinyl acetate (VA) content in 5%-40%, and polyethylene (PE) compared to EVA due to the molecular chain of the vinyl acetate monomer, thereby reducing the high crystallinity, improved toughness, impact resistance, filler compatibility and heat sealing performance, is widely used in foam material, functional films, packaging mold, hot melt adhesive, wire and cable and toys and other fields.
Q:Is ABS plastic poisonous?
Of course, due to the application of different plastics will add different additives, but the difference is very big. Different plastic plastic additives are generally inorganic filler, glass fiber, pigment, antioxidant, anti UV agent, plasticizer and inorganic filler and glass fiber. The body is stable and has no toxicity to the mineral glass. The human body. The antioxidant and anti UV agent general dosage is small, but 1-2% of the components, of course the nature itself is non-toxic or low toxic to the human body. The most likely risk of plastic is PVC, the plastic additive content could even reach 60-70%, it is difficult to ensure there is no harm to human body.
Q:How to make plastic shrink?
A reduction in the temperature of the plastic will shrink the plastic.Plastic is expansion and contraction, and the greater the general shrinkage, the more easily deformed plastic. Different plastics, shrinkage is not the same.
Q:How can plastics be broken down into harmless substances?
First of all, waste plastic packaging mixed in soil, affected crops absorb nutrients and moisture, will lead to crop failures; second, abandoned waste plastic packaging on land or in the water, animal as food ingestion, leading to animal death (in the zoo, pastoral areas and the sea, such a situation has It is often seen.); third waste plastic packaging, mixed with garbage in the landfill will be very difficult: long-term occupation of land, mixed with a plastic garbage is not suitable for composting, sorting out of waste plastic is also due to the quality assurance and difficult to recycle.
Q:POM plastic flower mold how to solve?
Plastic mold is the plastic processing industry and plastic molding machine matching, giving plastic products to complete configuration and precise size tools. Because of the plastic varieties and processing methods of various plastic molding machine and plastic product structure is simplified, so the plastic mold of the type and structure is various.
Q:What is the difference between the glue and rubber plastic products? What are the advantages and disadvantages?
It is special as plastic rubber particles, the particles of long and soft, good toughness, by stamping tilted to one side, causing the ball hitting the line erratic, sinking in the industry known as the "magic particles". Rubber is a kind of rubber between rubber and rubber, its performance has two sets of advantages, have a long shot, the counter rotating particles sinking characteristic, and has the advantages of good fast plastic particles.
Q:How many kinds of plastics are there?!
Plastic material can be divided into granular (such as calcium plastic reinforced plastic), fiber (such as glass fiber or glass cloth reinforced plastic), sheet (such as mica reinforced plastic) three. According to the material can be divided into cloth reinforced plastic (such as rags or reinforced asbestos reinforced plastics), inorganic mineral filled plastics (such as quartz or mica filled plastics), fiber reinforced plastics (such as carbon fiber reinforced plastics) three.
Q:What are the advantages and disadvantages of plastic wallpaper?
Long service life, plastic wallpaper and other wallpaper relative to, whether it is economic, functional or artistic, its comprehensive indicators are better, is a fully functional wall decoration materials.
