Pp foam board, also known as polypropylene foam board, is manufactured using polypropylene as the main raw material. During the production process, we use carbon dioxide gas to foam it. When propene is foamed, its density and thickness are controlled. The best density range is between 0.10 and 0.70 g/cm2, and the best thickness is between 1 mm and 2 mm. Out of the pp foam sheet has superior performance. Next Xiaobian introduced the properties of PP foam sheet and PP foam sheet manufacturers.
What is PP foam sheet
Pp sheet is a semi-crystalline material that incorporates random copolymers, glass fibers, metal additives, or thermoplastic rubber. It is also an engineering plastic. It is characterized by low density, chemical resistance, heat resistance, impact resistance, non-toxicity, and tasteless, but its low oxidation resistance, and can not resist aromatic hydrocarbon solvents, chlorinated hydrocarbon solvents, etc. Because of its characteristics, it is widely used in the manufacture of plastic water tanks, acid and alkali-resistant equipment, environmental protection equipment, waste water, and exhaust gas discharge equipment.
PP foam sheet properties
1, excellent heat resistance. Foaming PS is usually used at 80°C, foamed PE is only resistant to 70-80°C, and foamed PP is resistant to 120°C. The foamed PP was left at 120°C for 22 hours, and the dimensional shrinkage was less than 2%. Under the same conditions, the foamed PE contracted about 40%. Therefore, foamed PP can be used in applications where the temperature exceeds 100°C.
2, excellent mechanical properties. Take the Ace type PP foamed material of Japan Furukawa Electric as an example, its mechanical properties such as tensile strength and tear strength are in the highest grade of foam; its compressive strength is lower than that of rigid PUR and foamed PS, but softer than The PUR is high, ie it has a moderate compressive strength.
3, significant heat insulation. The foamed PP, like the foamed PE, has a closed cell structure, so its thermal conductivity is not affected by moisture. Due to its lower thermal conductivity than foamed PE and its significant thermal insulation, it can be used as an advanced thermal insulation material.
4, good resilience, and a high impact energy absorption capacity.
5, chemical resistance is better than all other foams; resistant to edible oils, to meet the needs of greasy food packaging.
6, good stress cracking resistance.
7. Compared with foamed PS, no toxic gas is emitted when burning.
8, can be recycled.
9, degradation performance is obviously better than foam PS and foamed PE.

Aluminium alloy is a type of metal that is widely used in various industries. This alloy is made by combining aluminium with some other metals, such as copper, magnesium, silicon, and zinc, to enhance its properties. The resulting alloy has improved properties than pure aluminum, such as higher strength, corrosion resistance, and good weldability.
One of the main advantages of aluminium alloy is its lightweight. It is about 1/3 the weight of steel, which makes it an ideal material for transportation applications, such as airplanes, cars, and trains. The alloy's high strength also makes it suitable for structural applications, such as in the construction industry.
The corrosion resistance of aluminium alloy is another benefit. Its protective oxide layer prevents rust and other forms of corrosion, making it an ideal material for outdoor applications, such as building facades, roofing, and window frames. The alloy's good thermal conductivity also makes it suitable for heat exchangers and other heat transfer applications.
Aluminum alloy also has a good aesthetic appeal. It can be easily shaped, welded, and fabricated into various shapes and designs. It can also be anodized or painted to provide a decorative finish.
In conclusion, aluminium alloy is a versatile material with many advantages. Its lightweight, strength, corrosion resistance, thermal conductivity, and aesthetic appeal make it an ideal choice for many applications.
