Plastic Heilex Ring 

Polypropylene Heilex ring has unique shape, which makes it not only has a large flux, low pressure drop, corrosion resistance and impact resistance, but also has other advantages, the polypropylene Heilex ring also has no nesting between packings, small wall flow effect and average gas-liquid distribution, etc. Polypropylene Heilex ring are suitable for gas absorption, cooling and gas purification process.
 

The basic property of Polypropylene PP
