Arotran ™ unsaturated polyester, epoxy vinyl ester and B-side resins
Arotran resins and resin systems can be utilized in the automotive and heavy-truck markets for both Class A and structural-part applications. Arotran resins can be utilized in a wide range of processes such as sheet molding compound (SMC), high-pressure resin-transfer molding, open-mold laminating, bulk-molding compounding (BMC) and infusion.
Arotran resin technology provides excellent mechanical properties, toughness and surface appearance. Arotran resins with Ekadure™ UV technology provides a molded-in black color that eliminates the need for paint with excellent UV stability.
Arotran Class A SMC and structural resins utilize nano-composite materials to provide original equipment manufacturers and molders with lower-mass SMCs which result in lighter parts. Parts made from Arotran Class A resins offer superior surface finish, reduction in paint pops, excellent bond and paint adhesion properties. Parts made from Arotran structural resins provide lower-mass structural parts with excellent mechanical and heat-resistance properties.
Arotran B-side resins are blended thermoset and thermoplastic-carrier resins that are combined with magnesium oxides to control thickening response.
Fabrication of body panels, e.g., doors, deck lids, roofs, hoods, fascia and fenders requiring Class A paintable finishes.
- Reduced paint pops
- Class A finish
Fabrication of UV-stable substrates for uses in pick-up boxes and tonneau covers.
- UV Resistant
- Superior toughness
Fabrication of reinforcement panels, e.g., hood inners, underbody shields, grill opening reinforcements, floor pans, valve covers and heat shields.
- Superior physicals
- Heat resistant
Mechanical testing provides test data to characterize the mechanical integrity of molded resin castings, composites, laminates and sections of molded parts. The data is used to qualify materials for customer specifications, to help design materials for optimum end-use performance or to evaluate the effects of exposure environments on mechanical integrity. The material strength can be evaluated in a variety of deformations:
- Tensile testing – measures the stiffness and strength of a material as it is being pulled apart in tension.
- Flex testing – measures the stiffness and strength of a material as it is being deformed in three-point flexural bending.
- Fatigue testing – applies to a cyclical load or strain to the sample and determines the resiliency or durability of the material by measuring the number of cycles to failure.
