Q: Main ingredients and formulations of PPR tubes: The main ingredient of PPR tube is polypropylene. The formula is simple. It is added color masterbatch. Suggest not to add any calcium powder and so on.

Q: What's the difference between recycled plastic bucket and plastic bucket made of raw material?: The biggest difference is strength. Do good strength, good performance. Recycled materials are generally impure and contain many fillings which are brittle and easily damaged.

Q: Raw materials for making plastic bags: Polyethylene (Polyethylene, PE), referred to as PE. It is a high molecular organic compound which is made up of ethylene. Polyethylene is recognized as the best food for contact with food in the world. Non-toxic, tasteless, odorless, in line with food packaging hygiene standards. Polyethylene film, light and transparent, with moisture-proof, anti - oxygen, acid, alkali, air tightness, heat sealing and other outstanding performance. Known as "plastic flower" laudatory title. It is the most important and most important material in plastic packaging and printing.

Q: How is plastic material made out?: At present, resins are polymers that have not yet been blended with additives. Resin accounts for about 40% to 100% of the total weight of plastics. The basic properties of plastics depend mainly on the nature of the resin, but additives also play an important role.

Q: Is the tableware made of PP raw material the best of those plastic tableware?: Polypropylene (PP) is made from propylene. The transparency is also better than polyethylene. It is harder than polyethylene. Most of the boxes packed in the hotel are made of it. The plastic boxes can be heated in a microwave oven.

Q: What are the materials for making plastic buckets? How many are there?: Domestic plastic bucket source material basically two kinds: blow molding with PE injection: PP

Q: What is Ms plastic material?: Transparent polymers were synthesized from methyl methacrylate (MMA) and styrene (SM) as the main raw materials.

Q: What are the raw materials needed for making plastic bags?: In addition, the bag color and performance requirements are not high, you can choose recycled polyethylene. Plastic can be recycled, because of the repeated use of processing, non-toxic, tasteless new plastic become cloudy, less than the original hygiene and color requirements. But this plastic bag is made from recycled material, which is environmentally friendly, and the price is 10% to 50% lower than that of the new material bag

Q: How about the price of plastic raw materials now?: ABS market overall stability, part of the small move.

Q: Chemical, plastic raw materials, plastic raw materials how sub grade?: That's because the raw material used for making plastic barrels is different. Just like the quality of the clothes, the grades of the fabrics used are different, and the products presented are definitely different.
