Linear Styrene-Butadiene-Styrene Rubber Sibur SBS L 30-01 A
Description
The linear styrene-butadiene-styrene thermoplastic is a product of block copolymerization of styrene and butadiene in a hydrocarbon solution in the presence of an organolithium catalyst. SBS L 30-01 A is dusted with calcium stearate or silica.
Key characteristics of the styrene-butadiene SBS L 30-01 A include:
- retains elasticity at low temperatures
- requires no vulcanization
- soluble in aromatic, cycloaliphatic and aliphatic solvents
- at normal temperatures exhibits the properties of vulcanized rubbers
Applications
Bitumen modification for road and roofing materials, plastics modification, footwear compounds, rubber goods, mastics and protective coatings.

Часто Задаваемые Вопросы
Сколько процентов СБС нужно класть в битум для модификации?
Различные марки СБС показывают разную эффективность, наиболее распространенным диапазоном считается 2-4% от массы вяжущего для асфальта. Такой процент экономически оправдан и существенно повышает свойства ПБВ, превосходя установленные стандарты.
