6、equirements. 2.1 Descriptions This specification covers several categories of material types with several choices within each category. The choices within each category typically vary by hardness and related physical properties but can apply to similar applications. The following base material desig

7、nations are available: 2.1.1 TPR This designates a standard thermoplastic rubber material. It usually consists of thermoplastic olefins (TPO) blended with elastomers, although other polymer bases are available. These materials may contain recycled rubber (post-consumer automotive tire) with prior ap
