What It Is

Interface Polymers is an innovative chemical company based in the United Kingdom, spun out from research conducted at the University of Warwick's Department of Chemistry. It focuses on developing high-performance plastic additives based on its proprietary diblock copolymer technology, with its flagship brand Polarfin®. Its core mission is to solve multiple common pain points in plastic recycling and processing, and advance the circular economy for the plastics industry. The company has already achieved large-scale production, begun supplying the global market, and secured investment from industry leaders including Evonik.

Core Functions & Products

The company currently offers three core product categories:

1. Polarfin® compatibilizers: Designed for mixed recycled plastics, they solve compatibility issues between different plastic materials. They improve the mechanical and optical properties of recycled multi-layer packaging plastics, enabling low-value mixed waste plastics to be used in high-value applications.
2. Long-lasting anti-fog additives: Powered by non-migratory technology, they deliver permanent anti-fog performance that outperforms traditional short-lived anti-fog solutions. They are ideal for applications such as agricultural film and medical protective face shields.
3. Adhesion promoters: They enable strong bonding of coatings and adhesives to polyolefin materials (polypropylene, polyethylene, etc.) without requiring pre-treatments such as corona or flame treatment, while preserving the recyclability of the plastic.

Advantages, Disadvantages & Suitable Use Cases

Advantages: The company's patented technology breaks through the performance limits of traditional additives. It delivers significant results at low loading rates, improves the quality of recycled plastics, and helps manufacturers cut costs and reduce energy use — perfectly aligned with industry goals for carbon neutrality and the circular economy. Large-scale production is already established, so supply capacity is reliable.
Disadvantages: As an industrial B2B company, the website does not disclose public pricing. Quotes and samples are only available after contacting the company directly, which creates a slightly higher barrier to entry for small and medium-sized manufacturers.

Accessibility from China

The website is currently fully accessible directly from China. Some core products already have Chinese-language technical datasheets available, and the company plans to attend industry exhibitions in Shanghai to expand into the Asian market. Relevant domestic enterprises can contact and inquire directly.
