Preform manufacturing
Products and manufacturing technologies are available for the large volume production of structural parts for the automotive industry. A CFRP reinforced body in white parts is made with HexPly M77 preforms from the company's automated process. The preforms' low tack allows for automated handling by the customer. They require no surface preparation and are designed for one-step bonding and curing in a press, requiring no finishing operations. Common BIW part joining technologies such as welding can be used, and the parts are said to be compatible with e-coating processes. The company's HexPly M77 resin cures in two minutes at 150°C, or 1.5 minutes at 160°C, and is available as HexPly M77 prepreg or as HexMC molding compound, which is said to be ideal for complex shapes. The gel time of M77 allows the resin to quickly flow into mold contours to achieve precise geometries, and the high Tg of 130°C enables cured parts to be demolded while warm for faster production cycles. Building on the attributes of HexPly M77, the company has installed a fully automated production line in Austria that converts UD prepreg into 2D preforms in seconds.

Automotive thermoplastics
Recent modifications to ECE R43 regulations are said to make Acrylite Resist AG 100 an ideal material for small quarter car windows. Prior to the regulation modification, requirements called for a coating to consist of scratch resistant materials. The highly transparent PMMA brand is said to offer the highest surface hardness of all thermoplastics, even without a coating, while offering a freedom of design that cannot be realized with glass, according to the company. Acrylite Resist AG 100 can be injection molded into almost any imaginable 3D shape. Panels can be produced with built-in wind deflectors and sharp angles, and the panels can be wraparound, according to the company. Based on the new regulation, Acrylite Resist AG 100 requires no additional coating for manufacturing a small panel because, unlike other transparent thermoplastics, the material is inherently resistant to UV light and weathering, allowing the panels to be manufactured in a single step. The modifications relate to all windows made of plastic that do not affect the driver's view. The surface area must be small enough that a circle of 150 mm diameter does not fit in the windows and the overall panel size must not exceed 200 cm2.

Styrenic TPEs designed for automotive exteriors
Styrenic TPEs designed for automotive exteriors A polymer-neutral product offering for automotive exteriors has been expanded by developing styrenic thermoplastic elastomers with alternative cost/performance profiles to those of widely used thermoplastic vulcanizates (TPVs). Sarlink ME-2200 series styrenic TPEs are said to exhibit higher flow than comparable TPEs, enabling molders of exterior components such as gaskets, seals and trim to process complex, intricate designs while shortening cycles through reduced packing and cooling time. In applications where TPV compounds are over-engineered, these TPE compounds are said to provide a cost savings while still meeting the performance requirements of the part. Like TPVs, the Sarlink ME-2200 series compounds are less dense than EPDM and PVC, yielding weight savings of up to 15% and 25%, respectively. Sarlink ME-2200 series styrenic TPEs are available in hardnesses from 65 durometer A to 40 durometer D. They are said to exhibit excellent UV stability, provide good flexibility over a wide temperature range, and yield a Class A surface appearance, according to the company. The compounds are readily colored and, unlike many TPVs, do not require pre-drying prior to molding. Sarlink ME-2200 series TPEs are already said to be in commercial use for static seals, cowl vent seals and mirror gaskets. All compounds in the series are available worldwide in both black and natural formulations. Besides the compounds for exterior parts, other styrenic TPEs from the company for automotive applications include the Sarlink ML-1100 and ML-1600 series for molded interior components, and a super high flow series, Sarlink ME-2600, for window encapsulation.

Shock absorber materials
Shock absorber materials With a high-performance material, the company is ensuring that shock absorbers can reliably do their job, even in extremely low temperatures down to -40°F. At the same time, the material mixture, which is coming into use in damper seals for cars and commercial vehicles, is said to be much more wear-resistant than conventional materials. Special low temperature polymers, which are crosslinked with peroxides, are used to extend the range of temperatures where fluoro rubber can be employed. However, elastomers produced in this way normally show increased wear. The company has found a way to combine actually incompatible material characteristics with one another. Another advantage of the material is that its frictional characteristics hardly fluctuate over the sequence of temperatures.
