Engineering Clarity with Enhanced Heat Resistance

Transform your transparent plastic applications with our Styrene Acrylonitrile portfolio, where crystal clarity meets superior heat resistance in a versatile engineering polymer.

Understanding SAN (Styrene Acrylonitrile)

Styrene Acrylonitrile represents a perfect marriage between styrene's clarity and acrylonitrile's heat resistance. This copolymer achieves its exceptional properties through precisely controlled incorporation of acrylonitrile units within the polystyrene backbone. Think of it as reinforcing a clear glass structure with heat-resistant pillars – the acrylonitrile content enhances thermal and chemical resistance while maintaining the outstanding clarity of styrene.

SAN Classifications

General Purpose Grades

Our general-purpose portfolio features MFI ranges from 12 to 25 g/10min, delivering excellent balance between processability and mechanical properties. These grades provide superior clarity comparable to GPPS while offering significantly better heat resistance. Their consistent processing characteristics make them ideal for injection molding applications where clarity meets functionality.

High Heat Grades

Engineered for demanding thermal applications, these grades feature MFI ranges from 15 to 30 g/10min with optimized acrylonitrile content. They offer enhanced heat deflection temperatures up to 108°C, making them perfect for applications requiring both clarity and thermal stability. The carefully controlled molecular structure ensures excellent dimensional stability even at elevated temperatures.

Easy Flow Grades

Our high-flow variants showcase MFI ranges from 25 to 40 g/10min, specifically designed for thin-wall applications and complex moldings. These grades maintain the exceptional optical properties of SAN while offering enhanced processability, enabling faster cycle times and more intricate designs without compromising mechanical properties.

Food Contact Grades

Specially formulated to meet global food contact regulations, these grades offer MFI ranges from 15 to 30 g/10min. They combine SAN's inherent clarity and heat resistance with carefully selected additives and stabilizers that ensure long-term safety in food contact applications. Their enhanced chemical resistance makes them ideal for reusable food containers and kitchen appliances.

Applications in Modern Industry

In the household appliance sector, SAN has revolutionized the design of water filtration systems and small kitchen appliances. The material's clarity allows consumers to monitor water levels and food processing, while its superior heat resistance ensures durability in daily use. From coffee maker water reservoirs to food processor bowls, SAN provides the perfect balance of aesthetics and functionality.

The cosmetic packaging industry leverages SAN's exceptional properties to create premium packaging solutions. The material's glass-like clarity showcases product contents beautifully, while its chemical resistance protects against the various ingredients found in cosmetics. The enhanced heat resistance ensures package integrity during manufacturing and filling processes, where temporary exposure to elevated temperatures is common.

In kitchenware applications, SAN creates durable, attractive products that withstand the rigors of daily use. From measuring cups to serving ware, the material's combination of clarity, heat resistance, and durability makes it ideal for both household and commercial kitchen applications. The enhanced chemical resistance ensures products maintain their appearance even with frequent dishwasher cleaning.
