Technical Details & Test Data
- KyronMAX® S-4240 DMA Stiffness
KyronMAX® materials are lightweight and, when molded, parts are 75% lighter than steel and almost 40% lighter than aluminum. By utilizing the lower density of KyronMAX®, customers can simultaneously realize lower costs and lighter parts, while also taking advantage of unmatched tensile and toughness properties.
The better “practical toughness” values are achieved with lower filler loading, which increases the material’s elongation at yield. KyronMAX® molded parts are more likely to yield, rather than fracture under high-stress loads. KyronMAX® stronger fibers and lower filler loadings further elevate molded product performance with significantly better knit line strength compared to other filled polymers.
Aluminum bracket with half FEA analysis (left) and KyronMAX® final molded part (right). The FEA analysis is used to translate a metal part into a lightweight plastic molded part, while matching or exceeding the strength and stiffness of the original metal part.
Mitsubishi Chemical Advanced Materials (MCAM) can take your metal parts and use our proprietary Finite-Element Analysis (FEA) to engineer a high-performance product with KyronMAXⓇ materials. MCAM's unique FEA data offers a solution to accurately predict the mechanical performance of a part in real world applications with key features including mechanical stress, plastic injection molding flow, fatigue, and motion.
