1. Background of the Customer’s Customized Blend Requirement
In the fields of plastics, engineering materials, and high-performance polymers, long-term material stability has become one of the most important requirements for end users.
With increasing demands for heat resistance, oxidation resistance, and weathering performance, conventional single antioxidant systems are often unable to meet the requirements of advanced applications. By combining different functional stabilizers at specific ratios, a Special Blend can provide synergistic protection and improve polymer processing performance and service life.
Recently, Ecochem received a customized Special Blend inquiry from Hexagon Industrial Canada.
The customer stated in their email:
“This is*** from *** industrial Canada, we have a requirement of special blend for our customers in Canada, please check the formulation and let me know if its possible to make that blend.”
The customer requested Ecochem to evaluate the production feasibility of the specified formulation and confirm whether the special blend could be manufactured.
The customer also provided product pictures and process information:
“I am also attaching picture and process for your reference.”
According to the customer’s project plan, the minimum contract requirement is:
“Our minimum requirement for the contract would be 50-60MT.”
This means the initial project demand is approximately 50–60 metric tons, requiring the supplier not only to have laboratory blending capability but also reliable industrial-scale production capacity.
2. Customer’s 6-Component Stabilizer Blend Formulation
The special blend consists of six functional polymer additives, including phenolic antioxidants, hindered amine light stabilizer (HALS), UV absorber, and phosphite antioxidant.
The formulation is as follows:
| Component | Function | Percentage |
|---|---|---|
| Phenolic Antioxidant 3114 | Phenolic Antioxidant | 24.5% |
| HALS 119 | Hindered Amine Light Stabilizer | 23.5% |
| MD 1024 | Phenolic Antioxidant | 17.5% |
| UVA 234 | UV Absorber | 12.5% |
| Phenolic Antioxidant 1330 | Phenolic Antioxidant | 11.0% |
| Phosphite Antioxidant 168 | Phosphite Antioxidant | 11.0% |
This formulation combines the advantages of different stabilizer systems:
- Phenolic antioxidants provide long-term thermal oxidation protection;
- Phosphite antioxidants improve processing stability;
- HALS enhances weathering resistance and UV durability;
- UVA 234 reduces polymer degradation caused by UV exposure.
Through synergistic effects, the blend improves the overall stability and service life of polymer materials.
3. Technical Challenges in Special Antioxidant Blend Production
Although this product is manufactured through physical blending, multi-component powder blending requires strict process control.
1. Accurate Formulation Control
The product contains six different additives with different ratios. The manufacturing process must ensure:
- Accurate weighing;
- Consistent formulation execution;
- Complete batch records.
Even minor deviations may affect the final material performance.
2. Powder Mixing Uniformity
Different additives may have variations in:
- Particle size;
- Density;
- Flow characteristics.
Insufficient mixing control may result in:
- Powder segregation;
- Uneven component distribution;
- Inconsistent product performance.
Therefore, proper blending process design and equipment selection are critical.
