Our coating solutions for the rubber and plastics industries
The rubber and plastics industries operate under demanding production conditions involving high temperatures, molten material buildup, difficult demolding operations, and accelerated corrosion risks. Sofiplast supports manufacturers in these sectors with a comprehensive range of surface treatment solutions specifically designed for rubber and plastics processing applications, including machine components exposed to raw or vulcanized rubber.
Our technical coatings are engineered to extend equipment lifespan, reduce adhesion and tooling fouling, eliminate the need for release agents, and improve process reliability while reducing maintenance costs and production downtime.
Technical challenges in the rubber and plastics industries
- Adhesion
- Clogging
- Abrasion
Key benefits of technical coatings

Surface engineering solutions for the rubber and plastics industries
Thanks to its extensive range of specialty coatings and tailored surface treatments, including polyurethane, LAML’COAT®, metallization, and fluoropolymers (PTFE, FEP, PFA, etc.) Sofiplast supports manufacturers in the rubber and plastics industries with tailor-made solutions designed for their specific production requirements.
These durable, high-performance treatments help reduce excessive adhesion, clogging, and mechanical wear.
Customer case study
Looking for a non-stick coating to reduce fouling on plastic welding equipment?
During the heat-sealing of films onto trays, molten plastic strongly adhered to the metallic surfaces of the customer’s production equipment, causing rapid fouling, welding defects, and frequent cleaning-related downtime.
Sofiplast solution
To address this issue, Sofiplast recommended the application of a fluoropolymer-based coating. This non-stick treatment creates a smooth, heat-resistant barrier that prevents molten material from permanently adhering to equipment surfaces.
Thanks to this solution, the customer was able to optimize production throughput while reducing material loss and scrap rates. Sofiplast once again demonstrated its ability to adapt coating solutions to the specific requirements of plastic welding processes.
Are your elastomer molds causing material adhesion and making demolding difficult? Are injection channels clogging too quickly and disrupting material flow? Are raw or vulcanized rubber deposits affecting tooling precision? Are your silicone or polyurethane parts sticking to mold surfaces despite the use of release agents? Are molten material deposits affecting the quality of your plastic welding or assembly processes?
