Polyplastics Develops New LAPEROS (R) Liquid Crystal Polymer (LCP) Grades with Improved Blister Resistance
TOKYO, Nov. 26, 2019 /Kyodo JBN-AsiaNet/ --

The Polyplastics Group has announced new developmental grades of LAPEROS (R) 
liquid crystal polymer(LCP) which offer superior blister resistance for 
electronic connectors. The two grades--currently in a pre-commercialization 
phase--have been confirmed to inhibit blistering more effectively than existing 
materials and show strong potential for improving productivity. Polyplastics 
has conducted experimental studies on different forms of blistering and is 
working to achieve an even greater reduction in blistering defects.


LCP is widely used in SMT(Surface Mount Technology) parts due to its strong 
heat resistance and flowability. Blistering is a common flaw for LCP which 
takes the form of bulges that appear on the surface of molded articles due to 
heat. Blistering has a variety of potential causes, including LCP decomposition 
gases that get entrapped during molding, and separation between the skin and 
core layers. 

Polyplastics noted the importance to use materials with higher heat stability 
and which also generate little gas. LAPEROS (R) LCP comes in a wide range of 
grades to accommodate customer needs, including ultra-high heat-resistant 
grades. The company has also conducted studies on nozzle and sprue optimization 
with the aim of offering solutions to blistering. Other factors such as molding 
conditions and mold shape design also have a strong influence on blistering.

In addition to high flowability and dimensional accuracy, LCP exhibits high 
heat resistance and is widely used in connector applications in devices such as 
smartphones which are becoming more compact and trending toward SMT. The 
automotive, home electronics, and office automation industries have also 
increasingly adopted LCP in recent years due to demand for high dimensional 
accuracy and heat resistance.
