TPR Environmentally Friendly Particles

Have you ever thought that the toothbrush handle you hold every morning, the touch of the headphone wire entangled during commuting, and even the sound of the suitcase wheels sliding across the ground are all closely related to a material called TPR environmentally friendly particles? This magical substance, which combines the elasticity of rubber and the plasticity of plastic, is silently reshaping the experience of modern life. Zhongsu is a factory that has been rooted in Guangdong for 21 years, using craftsmanship and technology to give TPR particles a soul.

Under a microscope, the molecular structure of TPR environmentally friendly particles is like a carefully woven network. Our R&D team is well aware that a 0.1% difference in formula may determine whether the grip is sticky or dry, and whether the wheels are quiet or noisy.

1. For the grip of sports equipment, we adjust the styrene content so that the material can still rebound quickly at a 30% stretch rate;

2. For food-grade straws, platinum catalytic system vulcanization is used to ensure that there is no odor migration during high-temperature brewing;

3. In the application of encapsulation, the special polar modification process increases the adhesion between TPR and PA (nylon) by 40%, completely solving the delamination problem.

These seemingly small numbers are actually the result of hundreds of laboratory iterations. A European customer once sent a sample of an aged and cracked yoga mat. We introduced nano-calcium carbonate and elastomer blends to extend the weathering life from 6 months to 3 years. This is the charm of material science.

Toy industry

When TPR becomes a bear doll in the palm of a child, safety becomes the only criterion. We abandon traditional plasticizers and use hydrogenated petroleum resin as a soft medium, so that the toy remains tough in an environment of -20℃ to 60℃. What is more worth mentioning is that the bright colors do not come from heavy metal dyes, but are achieved through inorganic pigment microencapsulation technology, which will not fall off even if bitten for a long time.

Medical field

The TPR seal ring where the respiratory mask fits the face needs to meet the three contradictory requirements of biocompatibility, creep resistance and easy cleaning at the same time. Our medical-grade particles are pre-treated by gamma ray sterilization, and the silicone chain segments are innovatively introduced to keep the material soft after repeated disinfection, so that patients cannot feel the existence of the material.

Industrial scene

The car fender has to withstand the dual test of gravel impact and ultraviolet exposure. Ordinary TPE is easy to become hard and brittle in this environment, while the dynamically vulcanized TPR (TPV) we developed uses cross-linked EPDM as the dispersed phase, so that the hardness of the product does not exceed 5 Shore A after the aging test at 120℃. An engineer from a Japanese car company commented: "It gives the parts the ability to 'self-repair'."
