Lubrizol Engineered Polymers launches, Pearlbond™ 920, a plasticizer-free thermoplastic polyurethane (TPU) for hot melt adhesives (HMA) for UV and color-stable material in outdoor applications. Pearlbond 920 TPU has superior weatherability, hydrolysis resistance and can be applied in sportswear, edge banding in furniture, interlinings, reflective tapes, automotive interiors and awnings.
High Bonding Strength with Heat Activation at Low Temperature
The TPU is soft and offers flexibility across a wide range of temperatures. Pearlbond 920 TPU can be heat-activated at low temperatures on a wide range of equipment such as extrusion (slot die, flat die, blown film and gravure roller coating machines) and powder coating making it the ideal choice when bonding delicate substrates such as leather. Pearlbond 920 TPU’s “wetting” properties ensure high bonding strength without compromising soft touch feel or flexibility.
Alternative materials like aromatic TPU under outdoor heat may discolor when exposed to light, leading to potential aesthetic problems first and performance failures later. Pearlbond 920 TPU offers mechanical properties with UV resistance, which allow products to be in use longer for the most demanding outdoor adhesive applications.
“
Lubrizol’s new grade is offering sustainability, durability and a strong bonding strength to a multitude of substrates such as PET, PA fabrics, cotton and many other textiles. It is potentially compliant of BlueSign® and Oeko-Tex® certifications, depending on the end use,” said James Ruben, business development manager for Engineered Polymers.
