PRODUCT APLICATIONS |
|
|
Yoho-38 provides outstanding thermal stability and electrical performance. It is particularly suitable for engineering plastic applications such as polyesters (PET, PBT, PCT) and polyamides (nylons). It has outstanding thermal stability , it is an ideal choice for high temperature applications such as engineering plastics . Due to its stability, it can often be used where other flame retardants fail to survive . Due to its polymeric structure , it is non blooming in all applications . Excellent electrical properties provide yet another reason to choose this flame retardant for demanding engineering plastic applications. |
