TPEs that minimise emissions from VOCs
Advantages
The Dryflex Interior series of TPEs offer on average a 75% reduction in emissions compared to other TPEs for interior applications in the market. Representative grades have been tested externally at accredited test laboratories.
The materials display low odour with results 2.0 to 3.0 in standards such as VDA 270. According to gravimetric fogging standard ISO 6452 they achieve condensate < 1.0 mg and VOC from 60 to 120 μg/g and Fog from 200 to 600 μg/g. They have also passed additional interior tests for lightfastness, flammability and mechanical performance.
Typical Applications
Applications include inlay mats in the dashboard, door, middle console or glove box. They are also well suited for thumb wheels, switches, cup holder liners, interior trim and HVAC components.
