Be able to bear or endure gallop applied case: PUR bubble is hot expand

PUR foamy heat expands behavior expands through heat appearance checks, institute of as above plan is shown, the anisotropy of material is not apparent. - the 160°C CTE value to the Y inside 100°C temperature limits and Z direction is almost same. Additional, undertook on every direction repeatability checks, as a result indication DIL 402 C expands appearance has good repeatability.
