Foaming Agents

Chemical Foaming Agents

Foam quality starts with the right chemistry. Chemical foaming agents generate gas within a polymer matrix during processing, creating the cellular structures that make finished products lighter, better insulating, and more cost-efficient to produce. Get the selection wrong and it shows up immediately — in foam density, surface defects, or process instability. Get it right and it runs quietly in the background, batch after batch.

Selecting the right foaming agent means matching decomposition temperature, gas volume, resin compatibility, processing method, and emissions profile all at once. That’s where product knowledge and supply reliability both matter.

ARP Materials supplies the full UNICELL portfolio of ACDA (D Series) and OBSH (OH Series) chemical foaming agents and activators manufactured by Dongjin Innochem, one of the world’s largest foaming agent producers. UNICELL products are used across automotive interiors, building materials, footwear, flooring, wall coverings, packaging, and more.

Physical Foaming Agents

Not every foam application calls for a chemical reaction. Physical foaming agents work by expanding rather than decomposing — either during processing or as pre-expanded fillers blended directly into a formulation. The advantages show up in tighter cell size control, cleaner processing, and better surface finish, particularly in applications where weight reduction and structural uniformity are priorities.

ARP Materials supplies two UNICELL physical foaming agent families: the MS Series (thermally expandable microspheres) and the HMS Series (pre-expanded hollow microspheres).
