highy quality white clear plastic hollow balls
Plastic balls is made from heat resistant and chemical corrosion resistant material , including HDPE, PE,PP, RPP, PVC, CPVC, PVDF. It has features such as high free volume, low pressure drop, low mass-transfer unit height, high flooding point, uniform gas-liquid contact, small specific gravity, high mass transfer efficiency and so on.It is widely used in petroleum and chemical, alkali chloride, gas and environmental protection industries etc.
PP(Polypropylene) Balls
plastic balls are made from Nylon, POM, PE, PTFE, PP, HDPE, or ABS, all of them could be customized.
Polypropylene Ballsare ideal for light load bearings and flow control applications. Often used in the construction of office furniture and medical equipment because of their quiet operation. Plastic balls are often used extensively in pharmaceutical, food and chemical production.

Mainly application:
Name | Application |
pp | Polypropylene ball are resisting into not concentrated acids,alkalis,alcohols,oils,grease and most inorganic compounds.Fair assistance in armatic hydrocarbons, they are not resistant in contact with halogens.They provide corrosive phenomena even in presence of concentrated acids and oxidizing agents at high temperature. |
PE | Excellent corrosion resistance in contact with acids, alcohols,basis,esters,petrol,grease and oils.Fairish resistance to aliphatic and aromatic hydrocarbons,mineral, oils,oxidizing. |
PVDF | Excellent corrosion resistance in contact with inorganic acids and salts,organic acids,alcohols,aliphatic and aromatic hydrocarbons,halogens except fluorines,oxidizing environments. They are not suitable against nearly pure strong acids and basis,liquid alcaline metals, strong polar solvents |
PTFE | Teflon balls provide exceptional corrosion resistance properties,they are resisting even in contact with industrial acids or caustic substances. They suffer corrosive phenomeza only against molten alkaline metals and fluorides at elevated temperature. |
