Polypropylene
Shop qualified Polypropylene sheets, rods, and parts. Polypropylene is a semi-crystalline thermoplastic. It has high impact resistance, strong and tough mechanical properties, and is resistant to various organic solvents and acid and alkali corrosion. There is a wide range of applications in industry, including packaging materials and labels, textiles, stationery, plastic parts and reusable containers of various types, thermoplastic polymer equipment used in laboratories, speakers, automotive parts, and polymer banknotes, is one of the common polymer materials.
Is Polypropylene good plastic？
PP ( polypropylene) is always considered and accepted safe for humans , it is a robust heat resistant please , it is unlikely to leach even when exposed to warm or hot water , and clients often choose this material to use for food and beverage storage . Nearly 50% of our clients who buy PP sheets , use them for food machinery food grade sheets . So PP should be safe and good plastic .
What is advantage of PP plastics？
PP plastics always been treated as PP rigid plastic sheets , the PP sheets have so many positive affects for our industry applications . Such as : it is readily available and relatively inexpensive ; It is very resistant to absorbing moisture : It is very suitable to weld water tanks because PP sheets and PP welding rods are the best plastic material for welding ;It has good impact strength ; It is good electrical insulator and it has good chemical resitance over a wide range of bases and acids .
What do we use polypropylene for？
We collect our clients who bought PP sheets application informations and list as below for your reference : industrial chemical tanks, medical trays, and fibers that are used to make indoor and outdoor carpeting .
Among this , welding is the main application for PP plastics , because this material is anti corrosion and very good at resistance chemicals , meanwhile it has a good affect with welding , so to make the water tanks , PP material become the best choice , through welding , workers use the welding gun and welding rod to make it a tight seam and it is excellent for producing tanks .
Besides , another big application is the Orthosis , we supply different size to clients for them to deeply process to make human orthosis .
How to choose PPH and PPC？
There are two grades of PP plastics , that is PPH and PPC .
They have very similar characters and cost , but their outlook , surface and properties still have some difference .
PPH is more harder and stronger than PPC , and it is used more widely , its price is a little higher , but it indeed has excellent properties , like excellent chemical resistance , the ability to be joined and welded by heat fusion . This character makes PPH to be choosed as the ideal plastic for chemical tanks and structures in corrosive environments .
PPC is more tougher and durable than PPH , it is a little cheaper , and it looks like a little softer , but it is more good in impact strength and tends to have better stress resistance and toughness , even in the low temperature , it can still keep very good property .
Can you list some detailed use of PP plastics？
We produce 25 and 32 mm thickness PPH sheets for orthosis .
And we make 12 mm PP sheets for welding water tanks .
Meanwhile we make flame retardant PP sheets , which used in underground waterpipe projects .
And another main use is the leather cutting factorys every two months will make order to us , request for 50 mm thickness PP cutting boards to cut leathers , they are from gloves , shoes , bags and leather factories .
How many forming method of PP plastics？
PP plastics can be made rigid sheets by extrusion , can be made rods by extrusion , and can be made special shape parts by molding injection .
No matter what kind of forms , PP plastics are always food grade and can be used in food machine and cutting plant and electroplateing process .
What are the disadvantages of polypropylene？
PP plastics is susceptible to ultrviolet degradation , meanwhile it is highly flammable , unless clients request to add anti flame additive when make sheets .
It is not resistant to oxidation , and not good at resistance to chlorinated solvents and aromatics .
Is polypropylene safe for skin?
Polypropylene is generally considered to be safe for skin contact, however, it can still cause skin irritation in some cases. It is important to take appropriate precautions when handling polypropylene, such as wearing protective clothing and using proper ventilation, to reduce the risk of skin contact.
Is polypropylene better than plastic?
It depends on the intended use. Polypropylene is generally considered to be one of the safer plastics, as it does not contain any known cancer-causing agents. However, it is not as strong as some other plastics and is not suitable for applications that require high strength or durability. Additionally, polypropylene is not biodegradable, so it is not an environmentally-friendly option.
