Wellamid® MRGF3822-BK

Technical Datasheet | Supplied by Wellman Engineering Resins (PRET)

Wellamid® MRGF3822-BK is a polyamide 66 grade reinforced with 38% glass fiber and mineral fiber. Addition of mineral to glass filled nylon reduces differential shrinkage disrupting the orientation of the glass fiber which results in more uniform shrinkage. Mineral with glass reduces the cost, improve dimensional stability and reduce warpage compared to standard glass filled nylons. Possesses high modulus, strength, HDT, excellent chemical and heat resistance. Used in automotive applications.
