Glass Epoxy laminates

KB-5150 is a CEM1 composite material with an inner core of epoxy/paper and outer plies of epoxy/glass. It offers many of the advantages of glass laminates at a price which is closer to that of paper laminates. KB-5150 is available either yellow or white with CTIs ranging from 175 to 600.

Product	Description	Properties	Downloads
KB-5150	CEM1 with good electrical/mechanical properties. UL94 V-0 and IPC-4101E/10 compliant White version / CTI 300 usually in stock	Suitable for warm punching at 45-70 °C with good hole quality. Excellent heat resistance, low warpage at high temperature Not recommended for PTH (because of cellulose core) Significant reduction in dusting,

Paper Laminates

Kingboard’s KB-2150GC sets the standard for high end paper-base laminate. It is a high strength paper/phenolic grade suitable for warm punching, and combines flame retardancy with the electrical/mechanical properties of a NEMA XX grade.
