Low melt strength and unstable molecular weight often cause uneven film thickness, poor tensile performance and low yield. Our high-purity PMDA (≥99.5% purity, ≤50ppm key impurities) acts as a high-efficiency chain extender: at 0.2% dosage, it increases PET intrinsic viscosity (Mη) by 9300g/mol (far exceeding BOZ), boosting melt strength, reducing defects and improving yield.
Thermal stability and mechanical properties are vital for high-end PET films (electronic insulation, flexible packaging). With decomposition temperature >500℃ and long-term service temperature >300℃, PMDA enhances film heat resistance, tensile strength and tear resistance for harsh environments. Its good compatibility with PET ensures uniform dispersion, avoiding performance inconsistencies.
Cost control and stable supply are critical to manufacturers. Our products can reduce costs by up to 40%, and we have stable delivery times and long-term export experience. We can also provide customized PMDA to match different PET film production processes.
In summary, our PMDA solves manufacturers' core pain points (quality, efficiency, cost) with high purity, excellent chain extension, stable thermal performance and cost advantages, making it your most reliable PET film production partner.
We also welcome all partners to contact us for samples and pricing.
