Brominated Polystyrene

Product Overview

Brominated Polystyrene (BPS) represents a class of high-performance polymeric flame retardants designed specifically for demanding engineering plastic applications. As a brominated organic compound, it offers superior thermal stability and compatibility compared to traditional low-molecular-weight alternatives. This product is synthesized through the controlled bromination of polystyrene, resulting in a robust additive that integrates seamlessly into various polymer matrices without compromising structural integrity.

Our manufacturing process ensures consistent quality, making it an ideal choice for industries requiring strict adherence to safety standards and mechanical performance. The polymeric nature of this flame retardant significantly reduces migration issues, ensuring long-term reliability in finished products. It serves as a critical component in achieving fire safety compliance while maintaining the aesthetic and physical properties of the base resin.

Technical Specifications

Industrial Applications

This specialized chemical is predominantly utilized in the modification of thermoplastic resins. It exhibits exceptional efficacy in engineering plastics such as Polyamide (PA), Polybutylene Terephthalate (PBT), and Polyethylene Terephthalate (PET). To achieve optimal flame retardancy, specifically targeting the UL94 V-0 rating at 0.8mm thickness, it is recommended to use this product in conjunction with antimony compounds as synergists.

Typical addition levels range from 10% for reinforced materials to 17% for non-reinforced formulations. This flexibility allows compounders to tailor properties according to specific end-use requirements, whether for automotive components, electrical housings, or industrial machinery parts. The compatibility with Polyphenylene Ether (PPE) and Nylon-66 further expands its utility across diverse manufacturing sectors.

Key Advantages

• Excellent compatibility with engineering plastic matrices due to its polystyrene backbone.
• Minimal impact on mechanical properties, retaining over 90% of the base material strength.
• Superior thermal stability suitable for high-temperature processing conditions.
• Low volatility ensures reduced fogging and cleaner processing environments.
• Classified as non-dangerous goods for simplified logistics and storage.

Storage And Handling

To maintain product integrity, store in a dry and ventilated warehouse away from direct sunlight. Avoid exposure to moisture and fire hazards. Keep containers sealed when not in use. The product is packaged in 25kg bags for convenient handling and inventory management. Proper storage conditions ensure the chemical stability and performance characteristics remain intact throughout the shelf life.
