We Shandong Hongrui Petrochemical is one of the largest manufacture of medium molecular weight polyisobutylene.

     Hongrui Company specializes in the production of low and medium molecular weight poly-isobutylene through various advanced production equipment. We cooperate with domestic research institutes and national key laboratories, using many advanced manufacturing processes to synthesize poly-isobutylene. We operate in strict compliance with ISO9000 quality management system, ensuring our stable, reliable and outstanding products.
     The shapes of “HRD” poly-isobutylene varies from fluid to elastomer according to the molecular weight. “HRD” poly-isobutylene is a kind of functional polymer material with the properties of colorless and transparent in terms of appearance, and nontoxic and odorless.
     Our products have high performance and characteristics of narrow distribution of molecular weight, low content of monomer and polymer, and stable properties. Especially the food grade poly-isobutylene, as a food additive, can meet the requirements of manufacturing and hygienic license for food additive in China.
