Muttenz, October 29, 2010 - Clariant presents an innovation for automotive plastics with the launch of unique UV stabilizer Hostavin® N845PP for polyolefin (PO) compounds for interior applications. In addition to UV protection, the new grade offers low fogging and low migration performance plus processing efficiency.
Migration is a significant concern for manufacturers of components such as dashboards, center consoles, and door cladding. Migration of a light stabilizer out of the PP part can cause undesired surface deposits or create a fogging effect on vehicle windscreens. Automotive manufacturers conduct rigorous testing at high temperatures to check for fogging potential.
Hostavin N845PP protects PO-based components against sunlight and artificial light degradation. Unlike other anti-UV active agents, it remains within the plastic and does not migrate to the surface of the component when exposed to heat. As a result Hostavin N845PP has a significantly reduced fogging and migration potential compared to other UV stabilizers.
This pioneering advantage is achieved through the grade’s excellent compatibility with the PO matrix. Hostavin N845PP is a 2-in-1 active ingredient, which means that the UV stabilizer is enclosed in a non-traditional carrier. The carrier ensures good processability of the PO compound, contributing to the knock-on performance benefits.
The 2-1 ingredient also creates a more efficient and safer processing environment. Supplied in granule rather than powder form, Hostavin N845PP is free-flowing and dust free. This enables compounders and masterbatch producers to control dosage levels more easily, allowing simple and efficient handling, and eliminates the potential for breathing in dust particles.
“When you add the UV protection and all the side benefits together, Hostavin N845PP brings a step change in performance and processing efficiency to plastics processors serving the automotive industry,” comments Ernesto Dongiovanni, Technical Head at Clariant. “We are looking forward to unveiling the advantages of our new innovation to K 2010 visitors.”
