Company Profile

In 1995, TPI POLENE Public Company Limited, our parent company, became the first ethylene vinyl acetate (“EVA”) manufacturer in South East Asia, with the current production capacity of 158,000 tons per annum.

The rapid growth in the development of renewable solar energy combined with our accumulated expertise in the field of EVA products has led to the “spin-off” of TPI ALL SEASONS Company Limited, a wholly-owned subsidiary established exclusively for the research and development and the commercial expansion of EVA Encapsulants for photovoltaic modules.

In 2007, the Company has successfully introduced our first series of Polene Solar® for commercial use in Thailand.


Polene Solar® are based on our own Polene® EVA resin with special additives for cross-linking and are best suited for both crystalline and thin film photovoltaic modules.

The development of Polene Solar® was made possible through the collaboration between Thailand’s Top-Tier Solar Cell manufacturers and our R&D team, who has over 10 years of experience in polymeric materials.
