Chemicals for the Plastics & Polymer Industry
The plastics and polymer processing industry depends on heat stabilisers, lubricants, flame retardants, and processing aids. MITCHEM supplies metal stearates (calcium, zinc, barium, magnesium), chlorinated paraffin, and zinc oxide as essential additives in PVC compounding, polyolefin processing, and engineering plastic formulations.

Calcium Stearate
CAS: 1592-23-0 | HS: 29157090
C₃₆H₇₀CaO₄ | 607.02 g/mol
In PVC processing, Calcium Stearate is an internal lubricant and processing aid, reducing friction during melt processing and improving surface finish on pipes, profiles, and sheeting.
Zinc Stearate
CAS: 557-05-1 | HS: 29157090
C₃₆H₇₀O₄Zn | 632.33 g/mol
Zinc Stearate is a primary heat stabiliser and external lubricant in PVC — in combination with calcium stearate (Ca/Zn stabiliser systems) it provides effective long-term heat stability meeting REACH and FDA requirements.
Barium Stearate
CAS: 6865-35-6 | HS: 29159009
C₃₆H₇₀BaO₄ | 704.28 g/mol
Barium Stearate provides excellent initial colour hold and transparency in rigid PVC applications. It works synergistically with zinc stearate in Ba/Zn stabiliser systems for balanced long-term stability.
Chlorinated Paraffin
CAS: 106232-86-4 | HS: 38122090
CₙH(2n+2-x)Clₓ | Variable
Chlorinated Paraffin serves as secondary plasticiser and flame retardant in PVC — reducing costs versus primary plasticisers while imparting fire retardancy to cables, floor coverings, and artificial leather.
Zinc Oxide
CAS: 1314-13-2 | HS: 28170010
ZnO | 81.39 g/mol
In plastics and rubber, Zinc Oxide serves as the essential vulcanisation activator in sulphur-curing systems — a function that cannot be replicated by other materials.
Magnesium Stearate
CAS: 557-04-0 | HS: 29157090
C₃₆H₇₀MgO₄ | 591.24 g/mol
Magnesium Stearate is used as internal lubricant in engineering plastics compounding, reducing equipment wear and improving melt flow in glass-fibre reinforced nylon and polycarbonate.
Aluminium Stearate
CAS: 637-12-7 | HS: 29159090
C₅₄H₁₀₅AlO₆ | 877.40 g/mol
Aluminium Stearate is used as thickening and anti-sagging agent in oil-extended PVC plastisols and high-build industrial coatings.
