Application
Application of H95 as an Antistatic Agent in Plastics
Due to its outstanding antistatic properties, emulsifying and dispersing capabilities, electrolyte resistance, and wetting properties, H95 has been successfully utilized in plastics as a highly cost-effective antistatic agent.
It is well known that the effectiveness of internal antistatic agents fundamentally depends on molecular structure, which determines key properties such as polarity and migration. The long carbon chain in the H95 molecule provides migration into polar plastics, while its polar groups confer hygroscopicity—the ability to bind moisture essential for forming conductive films. The ionic nature of the polar groups results in the highly conductive surface film formed by H95 when bound to moisture. Beyond the chemical composition of the antistatic agent, processing methods and ambient temperature also influence the speed and effectiveness of its action. The glass transition temperature of the plastic further impacts antistatic performance. For polymers with glass transition temperatures significantly above room temperature, the antistatic agent does not continuously migrate throughout the product's service life.
H95 is particularly suitable as an internal antistatic agent for plastics. When direct incorporation into polymers is impractical, its solubility in warm water (50–60°C) allows application as an aqueous solution (typically 40% solution) via spraying or surface immersion. The standard addition rate ranges from 0.1% to 2.0%.
① Application of H95 in Polystyrene
Typically, 1.5–2% H95 is added during polystyrene production and processing. However, note that concentrations exceeding 0.3% may cause haze in transparent polystyrene.
② Application of H95 in ABS
Processing ABS with 1.5–2.5% H95 achieves antistatic effects.
③ Application of H95 in PE
H95 is also suitable as an antistatic agent for polyolefins, particularly PE. It further improves melt flow. The recommended addition rate for PE is 1-2%. Unlike high-glass-transition polymers like PVC, PS, and ABS, antistatic agents in PE continuously migrate to the surface over extended periods, delivering long-lasting antistatic effects.
④ Application of H95 in PVC
The maximum dosage in rigid and flexible PVC is 3% (by weight).
2. Application in Textile Printing and Dyeing Auxiliaries
① Characteristics:
Mersolat H-95 is an exceptional anionic surfactant for specialized applications. Its low-concentration aqueous solution exhibits alkali resistance up to 40–80 g/L NaOH. A 40% active substance aqueous solution demonstrates outstanding rinsing performance with alkali resistance reaching 160–170 g/L NaOH.
Exceptional emulsifying capability; outstanding wetting performance under both strong acid and strong alkali conditions; treated fibers exhibit high moisture regain; excellent dispersion and foaming properties; outstanding biodegradability with a degradation rate of 99% (OECD certified); unique anionic antistatic agent capability; In aqueous formulations, exhibits resistance to strong acids, strong alkalis, sodium hypochlorite, electrolytes, and hard water; maintains broad stability and storage stability; virtually colorless and odorless with good skin compatibility and no irritation.
② Applications:
A. Mersolat H-95 is successfully used in pretreatment, dyeing, and post-treatment processes for various textiles due to its outstanding electrolyte resistance;
B. Serves as a raw material for specialty cleaning agents, wetting agents, and penetrants. Its low viscosity and high concentration facilitate ease of use. When blended with ANTIFOAMT, it achieves low-foam or foam-free effects.
C. Mersolat H-95 functions as a raw material for the following auxiliaries, compatible with nonionic surfactants or usable independently:
- Mercerizing penetrants, scouring agents, chlorine-bleach stabilizers in bleaching processes, antistatic agents and penetration rinsing agents in sizing/desizing processes, dye penetration agents, soap washing agents, alkali-resistant refining agents, antistatic agents, white background anti-soiling and anti-staining agents, desizing aids, leveling agents.
Package
20kg per bag, plastic packaging; 800kg per pallet.
When storing and using H95, special attention should be paid to the fact that this product is highly hygroscopic. When stored in its original, unopened packaging, the shelf life is 2 years.
