Scenario based application and adaptation solution of Beam Spacer in the tire industry
The core value of the Bead Spacer lies in adapting to different tire types' usage scenarios. PP material, with its customizable advantages, forms targeted solutions in the fields of passenger tires, commercial tires, engineering tires, and more. Based on specific application scenarios and adaptation data, analyze the practical value of Tire Plate.
In the storage and transportation scenario of passenger car tires, lightweight and slip resistance are core requirements. Conventional use of 1.0-1.5mm thick Circular plastic flaps with a density of 0.91g/cm ³ results in a single square meter weight of only 0.91-1.37kg, which is 25% lighter than traditional PVC partitions. Single batch transportation can save 12% of logistics costs. For the design of the arc-shaped contact surface of car tires, the PP bead separator adopts hot bending forming technology, and the bending radius can be customized to 150-300mm. The adhesion with the tire bead reaches over 98%, effectively dispersing the extrusion stress during storage and transportation. The actual test data of a mainstream car company shows that after using this bead separator, the scratch rate during tire transportation decreased from 8.3% to 1.7%, and the damage rate decreased by 72%.

Commercial vehicle tires have higher requirements for the strength and weather resistance of Apex Holders due to their high load and complex usage environment. Using reinforced PP bead separators with a thickness of 2.0-3.5mm, modified with 15% fiberglass, the tensile strength is increased to 32MPa, and the bending modulus reaches 1800MPa. It can withstand a stacking pressure of 8 tons per tire without deformation. In outdoor storage scenarios, PP tire bead separators with 0.4% UV resistant agent showed a tensile strength retention rate of 92% after 1000 hours of UV aging testing, with no cracking or discoloration, and an extended service life of over 4 years. In response to the large diameter characteristics of truck tires, PP bead separators with dimensions of 4000mm x 2000mm in length and width can be customized, combined with anti slip textures (surface roughness Ra=1.2 μ m) to prevent slip risks when stacked in multiple layers. ’
Engineering tires (such as loader and excavator tires) have strict requirements for the wear resistance and chemical resistance of PP bead separators. Using ultra thick PP tire bead separators with a thickness of 3.5-15.0mm, the surface is treated with silicon carbide coating, and the wear resistance coefficient is increased to 0.55. In the friction test with steel wheels, the accumulated wear after 5000 frictions is only 0.12mm. Its chemical resistance can withstand commonly used media such as diesel and hydraulic oil in construction machinery, and there is no swelling or deformation phenomenon after soaking for 72 hours. In terms of size adaptation, circular PP bead separators can be customized according to the diameter of the engineering tire bead (500-1200mm), with an inner ring tolerance controlled within ± 0.5mm to ensure a tight fit with the bead and avoid diaphragm displacement caused by vibration during operation.
