In particular, if silicone oil is added to improve the appearance by adding color, the creep resistance will be #
1. There is a drawback that you can't expect much. Furthermore, due to the fibrous shape of the glass fiber powder, the glass 111 fibers in the molded product tend to be aligned in one direction during molding, resulting in a directional imbalance in the physical properties of the molded product. The mechanical strength of the molded product differs in the molding direction (C, machine direction 2 or more, sometimes abbreviated as AI, D) and the direction that intersects it (sometimes abbreviated as C0D, the intersecting direction 2 or less). It becomes a product,
This has to be taken into consideration when designing and using a molded product, which is a problem with complicated and disadvantageous restrictions.
