Mitsubishi Gas Chemical's "ALTESTER" is a polyester resin that is heat-resistant, transparent, and safe for health. We would like to introduce three series. "S Series" - Heat resistance up to 95°C - Relatively high elastic modulus, allowing for rigidity and stiffness in thin or small containers and molded products - Can be mixed transparently with various polyesters such as polycarbonate, PET, PET-G, and PBT, controlling various physical properties such as heat resistance, refractive index, crystallinity, and moldability - High melt strength, can also be used as a foaming agent "SN Series" - Heat resistance up to 110°C - Can be mixed transparently due to matching the refractive index with PET, usable as a modifier. Recyclable - Has UV absorption properties, can be used as a UV absorber. Can suppress mold contamination and improve production efficiency "SH Grade" - Glass transition temperature is 135°C, no deformation after boiling for 1 hour - Amorphous with high transparency, impact resistance improved compared to existing grades, comparable to A-PET - Compatible with various molding methods (extrusion, injection, blow) * For details, please download the catalog or feel free to contact us.

We have newly developed a polyester resin called 'ALTESTER' that does not deform even at high temperatures of 95°C, with a transmittance of over 90%. It is heat-resistant and has excellent transparency, with heat resistance improved by over 30°C compared to conventional polyester, which deformed at around 65°C. - Maximum heat resistance of 95°C, usable in vehicle interiors and hot water - Excellent transparency, allowing for free molding through extrusion, injection, blow molding, and foaming - Low refractive index with total light transmittance of over 90%. High transmittance of visible light - Strong chemical resistance to acids, alkalis, alcohols, etc. - Easily blendable with polyester resins such as PET, PET-G, PBT, and PC.

The "ALTESTER SH Grade" is a special grade that has heat resistance and improved impact resistance. The impact resistance is higher compared to existing grades, on par with PET, and it has good chemical resistance as an amorphous polyester. Additionally, it has a Tg of 135°C and a total light transmittance of over 91%. It is a transparent material that demonstrates high heat resistance. 【Features】 ■ Glass transition temperature is 135°C, no deformation in boiling test ■ Amorphous with high transparency ■ Impact resistance is higher compared to existing grades, on par with PET ■ Good chemical resistance as an amorphous polyester ■ Listed in the Ministry of Health, Labour and Welfare positive list *For more details, please refer to the PDF document or feel free to contact us.

The "ALTESTER SC Grade" is a special grade designed to improve physical properties after stretching, possessing crystallinity. The resin has heat resistance with crystallinity and a glass transition temperature of over 100°C, exhibiting high Izod impact strength and excellent impact resistance even at low stretch. Additionally, the heat resistance of the stretched film surpasses that of PET, making it suitable for applications requiring high heat resistance. 【Features】 - Resin heat resistance: Crystalline with a glass transition temperature of over 100°C - Resin impact resistance: High Izod impact strength and excellent impact resistance even at low stretch - Stretched film heat resistance: Surpasses PET, suitable for applications requiring high heat resistance - Stretched film characteristics: Low density, low elastic modulus, low dielectric constant (compared to PET film) - Safety and hygiene: Under consideration for positive list inclusion *For more details, please refer to the PDF document or feel free to contact us.
