SINOPEC SBS 1801E is a linear styrene-butadiene-styrene (SBS) block copolymer specifically engineered for asphalt modification and waterproofing applications. With its stable structure, high elasticity, and outstanding compatibility with various grades of bitumen, 1801E has become one of the most trusted choices for road construction projects worldwide.
Compared with LG 411S, SINOPEC 1801E demonstrates equally strong mechanical and rheological performance, while offering a more cost-effective and stable supply.
Key advantages include:
Excellent Compatibility with Asphalt
Ensures uniform blending and stable performance during storage and transportation.
High Thermal Stability
Maintains elasticity and polymer integrity under elevated temperatures, reducing degradation risks during mixing.
Superior Aging Resistance
Delivers long-term durability and flexibility under harsh weather conditions, extending pavement life.
Smooth Processing
Enables fast and even dispersion during mixing, reducing energy consumption and production time.
Stable Supply and Competitive Pricing
Produced by SINOPEC, one of the world’s largest petrochemical companies, 1801E guarantees consistent quality and long-term availability — making it a sustainable alternative to LG 411S.
Polymer Modified Bitumen (PMB) for road paving and maintenance
Asphalt membranes and waterproof materials
Sealants and coatings requiring elasticity and crack resistance
Many of our clients in the Middle East, Africa and Europe have successfully replaced LG 411S with SINOPEC 1801E, achieving equivalent performance with measurable cost savings. Whether you are optimizing your asphalt formula or scaling up production, SINOPEC 1801E provides the balance between performance, reliability, and economy that today’s competitive market demands.
