rPET Modification: Sustainable Materials with Engineering Performance (BAITONG)

Under global sustainability requirements, manufacturers face a key challenge:

How to reduce carbon emissions while maintaining engineering-grade material performance?

BAITONG provides a complete rPET-based modification solution that delivers both sustainability and high performance.

1. Challenges of Recycled PET (rPET)

• High thermal sensitivity and IV loss due to multiple heat histories;

• Reduced melt strength and poorer fiber/filler dispersion;

• Large variations in toughness and mechanical properties;

• Higher hydrolysis risk and weaker long-term durability;

• Color instability, yellowing and black specks.

2. BAITONG rPET Additive System – Four synergistic components

1) Chain Extender BTCE‑9013

• Repairs chain scission and stabilizes IV;

• Even at 30–40% GF/mineral loading, overall property retention can exceed 85%;

• Improves melt strength and fiber wet‑out.

2) Nucleating Agent

• Compensates for weak crystallization ability in rPET;

• HDT can reach 190–210°C;

• Suitable for automotive and electrical components.

3) Toughening Agent

• Boosts impact strength by 200–300%;

• Reduces brittleness and stabilizes mechanical performance.

4) Anti‑Hydrolysis Agent

• Provides long‑term protection under hot and humid conditions;

• Critical for automotive, outdoor and transport applications.

3. Value Proposition

• Environmental: carbon footprint reduced by 40–60% vs virgin materials;

• Cost: 15–25% lower than virgin‑based modification;

• Performance: mechanical and thermal properties reach engineering‑plastic levels;

• Brand: enables ESG, circular economy and low‑carbon commitments.

4. Applications

• Automotive interior / structural parts

• Electrical & electronics housings

• Home appliance components

• Office equipment structural materials

BAITONG rPET modification solutions are certified by third‑party institutions and widely adopted by global brands,

making “green” the new definition of high‑performance materials.
