Detailed Description
Item nameSecurity seal plasticType of sealPull tightSecurity levelindicativeOperating temperature-40℃ to 60℃Total length400mmOperating length260mmsamplefree of chargePortQingdao port security seal plasticDescriptionProduction size: total length 400mmAverage tensile strength above 50lbs MaterialPolypropylene (PP)Polypropylene has high crystallinity and regular structure,Website:http://www.sdanguseal.com, so it has excellent mechanical properties. The absolute value of mechanical properties of polypropylene is higher than that of polyethylene, but it is still low in plastic material, and its tensile strength can reach only 30 MPa or slightly higher. Polypropylene with higher isotactic index has higher tensile strength.Strength, but with the increase of isotactic index, the impact strength of the material decreases, but it does not change after falling to a certain value.Temperature and loading rate have great influence on toughness of polypropylene. When the temperature is higher than the glass transition temperature, the impact failure is ductile fracture, which is brittle fracture below the glass transition temperature, and the impact strength decreases significantly. Increasing the loading rate can increase the temperature of ductile fracture to brittle fracture. Polypropylene has excellent bending fatigue resistance. Its products can bend 106 times at room temperature without damage.However, at room temperature and low temperature, the impact strength is poor due to the high degree of regularity of its molecular structure. The most outstanding performance of polypropylene is bending fatigue resistance, commonly known as 100 fold adhesive.
