Bitumen Modifiers

High-performance latex and polymer additives for enhanced bitumen formulations

Our bitumen modifiers include a range of latex and polymer-based solutions designed to improve the flexibility, durability, and weather resistance of both hot-applied and emulsion-based bitumen systems. These additives are widely used in building waterproofing applications such as roofing, basements, and wet areas. With options including SBR powder, SBR latex (SBR-40 and SBR-60), and SBS modifiers, we offer tailored solutions to meet the technical demands of modern bitumen modification.

SBS Bitumen Modifier:SBS modifier for modified bitumen

SBR Bitumen Modifier:

SBR (Styrene-Butadiene Rubber) bitumen modifier is a versatile and economical solution for enhancing the flexibility, water resistance, and workability of bituminous materials. Especially suitable for spray-applied coatings, bitumen emulsions, and liquid waterproofing, SBR modifier improves low-temperature performance and crack resistance with excellent cost-performance balance.

Used widely in residential, commercial, and light industrial waterproofing, SBR bitumen modifier helps you deliver reliable, consistent quality while optimizing production costs. It blends smoothly into bitumen emulsions and is highly compatible with anionic and cationic systems alike.

SBR Powder for Modified Bitumen

SBR powder is a dry, free-flowing styrene-butadiene rubber designed to be directly blended into hot bitumen during the production of waterproofing membranes and coatings. Its powder form ensures ease of storage and transportation while providing excellent modification performance. Once incorporated, it significantly enhances the elasticity, crack resistance, and weather durability of the bitumen system.

Key Benefits:

Easy to handle and dose, suitable for batch or continuous production

Improves aging resistance, tensile strength, and elongation

Enhances flexibility at low temperatures and softens thermal brittleness

Compatible with various fillers and additives in modified bitumen formulations

Application Scenarios:
Used in torch-on membranes, self-adhesive sheets, liquid-applied waterproofing systems for basements, foundations, and retaining walls.

Rubber Latex for Emulsion Bitumen – SBR-40

SBR-40 is a high-quality styrene-butadiene rubber latex with ~40% solid content, specially formulated for use in anionic or cationic bitumen emulsions. It provides improved cohesion, water resistance, and substrate adhesion without significantly increasing viscosity. The balanced formulation makes it ideal for spray-applied or brush-applied waterproofing emulsions.

Key Benefits:

Stable dispersion compatible with most bitumen emulsion systems

Enhances film flexibility, crack bridging, and substrate bonding

Maintains excellent performance under high humidity or wet substrate conditions

Reduces surface tack and improves workability

Application Scenarios:
Cold-applied waterproof coatings for bathrooms, balconies, and internal wet areas; suitable for flexible roof and wall membranes.

Rubber Latex for Emulsion Bitumen – SBR-60

SBR-60 is a high solid content latex (~60%) designed for advanced emulsion bitumen modification. It offers superior rubber reinforcement, making it ideal for high-performance waterproofing coatings requiring extreme flexibility, elongation, and resistance to aging and UV exposure. SBR-60 is especially effective in two-component or polymer-modified emulsion systems.

Key Benefits:

High solid content ensures strong modification effect with low dosage

Excellent water resistance, elongation, and recovery after deformation

Boosts durability and lifespan of bituminous coatings

Stable under long-term storage and compatible with various emulsifiers

Application Scenarios:
Ideal for demanding waterproofing jobs such as tunnel linings, external basement coatings, roof systems, and bitumen emulsions used in foundation protection.

SBS Bitumen Modifier:

SBS (Styrene-Butadiene-Styrene) bitumen modifier is a top-tier thermoplastic elastomer designed to dramatically enhance the performance of bituminous materials. Known for its superior elasticity, outstanding temperature resistance, and exceptional durability, SBS modifier transforms standard bitumen into high-performance waterproofing membranes and coatings.

Whether used in roofing, bridge decks, or below-grade applications, SBS modifier delivers long-lasting protection against cracking, fatigue, and weathering. It ensures that waterproofing systems remain flexible, resilient, and reliable even under extreme conditions.

SBS Modifier for Modified Bitumen

SBS (styrene-butadiene-styrene) modifier is a thermoplastic elastomer that provides outstanding elasticity, resilience, and thermal stability when mixed with hot bitumen. It forms a physical network within the bitumen matrix, creating a rubberized structure that maintains flexibility even under extreme temperatures.

Key Benefits:

High resistance to deformation, cracking, and UV aging

Maintains elasticity and mechanical integrity across a wide temperature range

Improves fatigue resistance and lifespan of waterproofing membranes

Forms smooth, uniform membranes with excellent adhesion

Application Scenarios:
Widely used in the production of SBS-modified waterproofing membranes for roofs, bridges, underground structures, and high-performance protective coatings.
