FRENCH specialty chemicals Arkema introduces a new addition, next generation high rubber impact modifier to their Durastrength line.
In white powder form, Durastrength 350, a high efficiency acrylic impact modifier provides exceptional toughness to weatherable PVC applications, says Arkema.
It is designed to provide the impact resistance required in modern construction formulations. Durastrength 350 acrylic impact modifier provides outstanding impact properties over a wide processing window for rigid vinyl products. It also possesses unique properties that are excellent for window profiles, siding, and capstock, where long-term weather resistance is necessary, and impact and colour retention are key. The low melt viscosity and rapid fusion characteristics also provide optimum conditions for difficult injection moulding applications.
