1. Plastics and Synthetic Materials

Auxiliary antioxidant for resins such as ABS, PVC, polypropylene (PP), and polyethylene (PE).

Significant effect when used in synergy with phenolic antioxidants (such as 1010 and 1076); non-polluting and non-staining, suitable for light-colored products.

2. 고무 제품

Auxiliary antioxidant for natural and synthetic rubber products.

Improves the thermal and oxidative stability of rubber.

3. 식품 산업

Antioxidant for edible oils, oily foods, and fried foods; fruit and vegetable preservation.

Good thermal stability, suitable for baking and frying processes.

4. 식품 접촉 재료

Used in paper and paperboard materials and products.

Must comply with national food safety standards (GB 9685-2016), with specific migration limits.

5. Lubricating Oils and Industrial Oils

Added to lubricating oils, greases, and other industrial fluids.

Improves the oxidative stability of oils and extends their service life.

6. Scientific Research and Other Fields

Used as a biochemical reagent in life science research; its skin antioxidant effects are studied in cosmetics. Primarily for laboratory use; potential applications in the daily chemical industry.

💡 Usage Points and Precautions

In practical applications, understanding the following technical details can help you better utilize this antioxidant:

시너지 효과: DLTDP is usually not used alone as a primary antioxidant, but rather in combination with phenolic antioxidants (such as BHT, 1010) or UV absorbers, producing a synergistic effect of “1+1>2,” improving stability while reducing costs.

복용량: In plastics and rubber, the recommended dosage is generally 0.05% to 0.5% (by resin weight). In food, the limit of 0.2 g/kg must be strictly adhered to.

Limitations: Its main drawback is its relatively high volatility, which may lead to losses under high-temperature processing conditions. Several improved products (such as TPI 2000) are currently available on the market to overcome this drawback.
