What is the difference between plastic particles and raw materials?
- PP recycled plastics profile: polypropylene (PP) - coloring not translucent, waxy, lighter than polyethylene, transparency is better than polyethylene, polyethylene than rigid. Mainly used for pots, barrels, furniture, thin film, woven bag, packing tape, bottle cap, car bumper.PE recycled plastics: Polyethylene (PE) - no coloring milky white translucent, waxy; touch smooth feeling, soft and tough, slightly elongated, generally low density polyethylene is relatively soft, good transparency, high density polyethylene hard. Mainly used for plastic film, bag, water, oilPS is polystyrene plastic. It is easy to dye and transparent. It is used to make lampshade, toothbrush handle, toy and electrical appliance parts. It is resistant to acid and alkali corrosion, but easily soluble in chloroform, two vinyl chloride, banana water and other organic solvents.s
What are the raw materials for producing plastic vest bags?
- Determine specifications, dimensions, and printed documentsAbout vest bag specifications, similar, non uniform specifications, can be customized according to customer requirements. General specifications such as 20*32cm, 25*40cm, 30*48cm, 35*55cm. Thickness according to plastic limit standard is single layer, not less than 0.025mm.Printed documents can be designed according to the sample, or delivered to the manufacturer by the customer, and may also be designed by the manufacturer.Carry out film blowing according to order quantity, and contact plate making process at the same timeBlown film is a plastic processing technology that melts plastic particles, melts them through an extruder, and then blows them into a plastic film through a blower. The plastic vest bag is made of high-density polyethylene (HDPE, also known as low pressure material) as raw material.s
What does plastic material include?
- Plastic bags are the main raw materials of polyethylene and polyvinyl chloride, are non degradable. The main raw material for the production of plastic bags and polystyrene, polypropylene polymer, waste plastic packaging into the environment, because of its difficult degradation, will cause deep ecological environment problems, the long time. Waste plastic packaging is mixed in the soil, affecting crops absorb nutrients and moisture, will lead to crop failures; abandoned waste plastic packaging on land or in the water, animal as food ingestion, will lead to the death of the animal.s
What are the raw materials of plastics made of?
- Synthetic resin refers to coal, petroleum, natural gas, calcium carbide and some agricultural products as the main raw material, the low molecular weight compounds prepared firstly has certain synthetic conditions (monomer), and then through chemical and physical methods for the synthesis of high molecular compound. The characteristics of this kind of compounds similar to natural resin (such as rosin, shellac, amber, etc.), but the performance and more superior than the natural resin.s
Plastic pipe gas temperature 150 degrees, plastic pipe surface problems?
- Plastic pipe is usually plastic resin as raw material, adding stabilizers, lubricants, etc., to "plastic" method in the pipe mill by extrusion processing. Because of its light weight, corrosion resistance, beautiful appearance, no bad smell, easy processing, convenient construction and other characteristics, it has been more and more widely used in building engineering. Mainly used for building construction of the water supply system, piping, drainage, exhaust and sewage sanitary pipe, underground drainage pipe system, storm pipe and wire installation supporting the use of threading tubes, and so on.s
What is the material of plastic dip?
- DIP processing, in general domestic PE dip powder or PVC dip plastic liquid. Specific depends on product characteristics and characteristics. Under normal circumstances, outdoor products, such as large pieces of metal products, PE dip plastic powder used for dipping plastic processing. PVC dipping liquid is more used for anti-skid products.s
Is plastic raw material rubber?
- Raw materials are polymers of polymers such as polypropylene. Is generally from the fossil raw materials inside the extraction after polymerization together. A series of plastic refers to the resin as the main component, such as plasticizers, fillers, lubricants, additives such as colorants as auxiliary components, can flow in the process of forming materials. To put it simply, the oil was extracted and finally made into plastic, rubber and plastics
