Polyscope unveils hybrid PP/SMA compound for automotive.
Polyscope Polymers BV, a specialized manufacturer of styrene maleic anhydride (SMA) copolymers, has introduced Xiloy, a polypropylene-based compound for the automotive market. This hybrid alloy is a semi-crystalline PP that is rigidified with an amorphous SMA, thereby offering a wider processing window and a more form-stable end product.
In an Oct. 24 interview at the K 2016 trade show in Dusseldorf, Germany, Polyscope CEO Patrick Muezers said the new PP/SMA material is a 30% glass-filled injection molding compound designed for applications that require high stiffness and strength, such as instrument panels. He says the new material's composition allows it to avoid the shortcomings of current PP-based materials that are widely used in IPs, whose crystallinity tends to limit their ability to withstand internal stresses.
Noting that Xiloy already has passed critical airbag-deployment tests, Muezers said the material delivers dimensional stability, stiffness and high thermal stability, making it well-suited for parts that require high temperature resistance along with low mold shrinkage and warpage.
The new product complements the 10-year-old Dutch firm's existing Xiran[R] portfolio of SMA/ABS compounds that automakers have been using in structural parts--such as sunroof frame systems--for many years. "We have a limited, narrow product range--all related to SMAs," Meuzers said. "We could do more, but our aim is to focus on this technology only."
