Articles for Pleated insect screens / Pull cords

Pull cords with Vectran® and Dyneema® for pleated insect screens. For pleated insect screens we have recently developed a cord where polyester and Vectran® are combined in order to achieve high performance and a cost-efficient solution. The cord shows promising results.

High-tech fibres for super strength

We are constantly researching and experimenting with innovative textile fibres to improve product properties. Textile articles with Kevlar® help provide lightweight strength, flexibility and temperature resistance and new high performance fibres like Vectran® and Dyneema® provide stronger textile articles with many advantages. We believe high performance fibres can make a cost-efficient replacement for many existing steel or fiberglass solutions.
