APTIV FILMS 1103 Series

The APTIV™ 1103 range of films are 30% mineral filled, semi-crystalline films manufactured from VICTREX™ PEEK polymer, developed to support engineers designing for ultra-high performance environments where dimensional stability and mechanical robustness are critical. Positioned within the broader APTIV film portfolio, the 1103 range provides an optimized material solution where enhanced stiffness and thermal stability are required beyond unfilled film grades.

APTIV films represent a versatile range of high-performance thermoplastic films that can enable reduced system costs, improved component reliability, and greater design freedom. The APTIV 1103 range combines high temperature capability with mechanical strength, durability, and excellent resistance to radiation, hydrolysis, and aggressive chemicals. The films also deliver electrical insulation, excellent barrier performance with high purity, low moisture absorption, and favourable flammability performance without the use of flame retardants, while maintaining low toxicity of combustion products.

Compared with the APTIV 1000 series, the mineral filled structure provides higher modulus and a lower coefficient of linear thermal expansion, supporting applications that demand improved dimensional control under thermal and mechanical load.
