Tek-Sil® SCH Materials (BETTER PERFORMANCE)
Tek-Sil® SCH Materials
BETTER PERFORMANCE
Tek-Sil® SCH is made using the same compound as "SH". Without fiber glass reinforcement thermal resistance improves from .26 degrees for "SH" to .18 degrees for "SCH". This material has a smooth, conformable surface.
