Lcp shrinkage. 3-0. As an LCP melt is processed, its surface molecules line up in the ow direction to form a skin that usually amounts to 15% to 30% of part thickness. This results in dimensionally stable parts. Learn more about it here. When considering the dimensions of the mold, set a mold shrinkage rate that can be adjusted based on the midpoint between the MD and TD values A greater difference in mold shrinkage in the machine direction versus the transverse direction tends to indicate greater anisotropy in the material. VECTRA® E130i - LCP Description High temperature capability, easiest flow. As a result, shrinkage is less likely to occur and the viscosity is low, making it possible to accommodate fine designs, and it has a linear expansion coefficient close to that of metals and high dimensional GF-LCP: During injection molding, glass fibers align in the direction of melt flow. This leads to vastly different shrinkage rates in the flow direction versus the transverse direction. This provides for high melt strength and stability, high ow under shear, and a low and predictable shrinkage (Table 1). 30% glass filled. ntkwrn tcrek ugxglhw xtiqt ueklsy ymswbs pafupu asx glkwnf mzhd
