TPU PPF Material Fundamentals
\nTPU (Thermoplastic Polyurethane): Self repair achieved through dynamic recombination of molecular chains, capable of repairing fine scratches at room temperature and achieving higher repair efficiency at high temperatures (such as above 60 \u2103)
\nPPF (\u041f\u043b\u0456\u0432\u043a\u0430 \u0434\u043b\u044f \u0437\u0430\u0445\u0438\u0441\u0442\u0443 \u043b\u0430\u043a\u043e\u0444\u0430\u0440\u0431\u043e\u0432\u043e\u0433\u043e \u043f\u043e\u043a\u0440\u0438\u0442\u0442\u044f<\/a>): Multi layer polyurethane structure, strong impact resistance, but self-healing ability depends on TPU substrate
\nPrinciples of self-healing and thermal repair
\nSelf repair: TPU soft segment molecular chains temporarily shift after scratches, and are restored to their original state through thermal activation (such as sunlight, hot water), repairing scratches \u2264 40 \u03bc m
\nThermal repair: requires a high temperature of over 60 \u2103 and sufficient molecular chain activity to achieve deep repair, but repeated repair may cause “memory damage”
\nTechnical Comparison and Selection Suggestions
\nRepair efficiency: TPU can repair quickly at room temperature (3 seconds), while PPF requires high temperature and has low efficiency
\nApplicable scenarios: TPU is suitable for daily minor damage, PPF is more suitable for high impact environments
\nAvoiding pitfalls: Poor quality TPU is prone to yellowing, genuine products require verification of anti-counterfeiting codes and professional construction<\/p>\n
