Linear Styrene-Butadiene-Styrene Rubber Kumho KTR 101
Description
A linear block copolymer containing styrene and butadiene. Styrene mass fraction is 31.5%.
Key characteristics of the styrene-butadiene Kumho KTR 101 include:
- increases the softening temperature of bitumen
- reduces sensitivity to temperature changes
- improves low-temperature flexibility
- improves elasticity and resistance to impact loads
- extends the service life of road surfaces
Applications
Bitumen modification (road surfaces and roofing), plastics modification, adhesives, shoe soles.

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.
