Performance/Purpose

NONFLEX WS is a non-staining antioxidant that effectively suppresses oxidation degradation and prevents the growth of flex-cracks. It has good dispersibility, eliminating concerns about blooming. Additionally, it has minimal impact on scorch and vulcanization.
Packing : 15kg can / 200kg drum
CAS RN : 61788-44-1

Appearance and Characteristics

Appearance : White to pale yellow powder
Ash : 35.0% max.
Heating loss : 5.0% max.

Performance/Purpose

NONFLEX WS-P is a solidified form of the liquid NONFLEX WS, achieved by combining it with silica. It offers the same performance as NONFLEX WS.
Packing : 20kg paper bag
CAS RN : 61788-44-1, 112926-00-8

Appearance and Characteristics

Appearance : White crystals
Freezing point : 69.0℃ min.
Ash : 0.01% max.
Moisture : 0.2% max.

Performance/Purpose

BHT SWANOX is a non-staining antioxidant without any coloring. When used in rubber applications, it not only provides oxidation prevention but also exhibits excellent flex-crack resistance and copper corrosion prevention effects. It is a versatile phenolic antioxidant widely used for various purposes.
Packing : 20kg paper bag
CAS RN : 128-37-0

Appearance and Characteristics

Appearance : Grayish white powder
Melting point : 208℃ min.
Ash : 0.3% max.
Heating loss : 0.3% max.

Performance/Purpose

NONFLEX ALBA is a non-staining antioxidant that demonstrates effective protection against heat and oxidation degradation.
Packing : 10kg paper bag
CAS RN : 88-58-4

Appearance and Characteristics

Appearance : White powder
Melting point : 125℃ min.
Ash : 0.3% max.
Heating loss : 0.3% max.

Performance/Purpose

NONFLEX MBP is an antioxidant that demonstrates effective protection against heat and oxidation degradation, as well as providing weather resistance not only for rubber but also for synthetic resins. When used in conjunction with NONFLEX RD, its effectiveness is further enhanced.
Packing : 20kg paper bag
CAS RN : 119-47-1

Appearance and Characteristics

Appearance : White powder
Melting point : 120℃ min.
Ash : 0.2% max.
Heating loss : 0.3% max.

Performance/Purpose

NONFLEX EBP exhibits the same performance as NONFLEX MBP, but it has better weather resistance compared to MBP. It shows reduced discoloration due to aging in ABS resin and latex, and it also has excellent viscosity stability.
Packing : 20kg paper bag
CAS RN : 88-24-4

Appearance and Characteristics

Appearance : White to off-white powder
Melting point : 132℃ min.
Ash : 0.1% max.
Heating loss : 0.3% max.

Performance/Purpose

NONFLEX CBP is a non-staining antioxidant without any coloring. It demonstrates a remarkable increase in effectiveness when used in larger quantities, and when combined with NONFLEX MB, it significantly improves heat resistance. Additionally, it exhibits excellent flex-crack resistance and metal corrosion prevention effects.
Packing : 20kg paper bag
CAS RN : 77-62-3

Appearance and Characteristics

Appearance : Pale yellowish transparent viscous liquid
Specific gravity (25℃) : 0.980 – 1.000
Refractive index (25℃) : 1.520 – 1.530
Viscosity (mPa・s/25℃) : 4500 – 7000
Color (APHA) : 200 max.

Performance/Purpose

NONFLEX TNP is a secondary antioxidant that exhibits excellent heat and oxidation degradation prevention when used in conjunction with amine-based antioxidants or phenolic antioxidants. Particularly when combined with phenolic antioxidants, it offers the potential for non-staining improvement in heat resistance.
Packing : 17kg can
CAS RN : 26523-78-4

Appearance and Characteristics

Appearance : Pale yellowish powder
Melting point : 280℃ min.
Ash : 0.3% max.
Heating loss : 0.3% max.

Performance/Purpose

NONFLEX MB is a secondary antioxidant that demonstrates excellent heat and oxidation degradation prevention when used in conjunction with amine-based antioxidants or phenolic antioxidants. Its outstanding resistance to solvent extraction also enhances its effectiveness in preventing heat and oxidation degradation. Additionally, it is effective as an antioxidant for PO (polyolefin) crosslinking.
Packing : 10kg paper bag
CAS RN : 583-39-1
