Celogen® Chemical Foaming Agents are nitrogen foaming agents used in expanded cellular rubber and plastic applications to produce a wide range of closed cell products.  These products are non-staining, odorless, emit a large gas volume, exhibit an ideal decomposition range, do not affect the cure, disperse readily, and can be mixed in a Banbury mixer.

Common applications include continuously extruded automotive profiles, insulation tubing for refrigeration and low pressure steam lines, press-molded closed cell sheets for moisture seals, shock absorbing sheets, and cellular soling.

Lion Copolymer manufactures Celogen® Chemical Foaming Agents in conjunction with one of the largest petrochemical companies in China, Jiangsu SOPO Corporation, at an ISO 9001 certified facility.

Royalene EPDM Elastomers is a terpolymer of ethylene and propylene, and a non-conjugated diene. The main attributes of EPDM are its electrical properties and outstanding resistance to oxidation, ozone, and the effects of weathering.  Royalene EPDM Elastomers is highly extendable, allowing high levels of fillers and plasticizers to be added while maintaining good physical properties.

Common applications include automotive weather seals, hoses, tire sidewalls, single-ply roof membranes, and wire and cable insulation. 

Lion Copolymer operates the largest EPDM plant in the world, with three dedicated operating lines.
