Material tear strength and hardness are important, but product geometry, mold design, curing, demolding, packaging and actual use conditions must also be evaluated before mass production.<\/p>\n<p data-start=\"1393\" data-end=\"1507\">A <a href=\"https:\/\/www.lyasilicone.com\/pl\/\">produkt silikonowy<\/a> can feel soft and flexible but still tear during demolding, assembly, cleaning or
