As the direct producer of SBS YH-791H, we serve specialized manufacturing sectors that require precise thermoplastic elastomer performance for demanding applications. Our formulation experience and industrial partnerships demonstrate validated use cases in downstream processes, each governed by rigorous standards and necessitating material consistency across batch production and quality control. Below, we outline real industrial sectors where SBS YH-791H plays a critical processing role, specifying regulatory frameworks, typical formulation ratios, process integration stages, and representative finished goods.

1. Modified Asphalt for Road Paving

Road material manufacturers utilize SBS YH-791H to impart flexibility, improved rutting resistance, and cracking resilience to bitumen-based asphalt. The controlled molecular structure of this grade supports enhanced thermal performance over broad temperature ranges, meeting region-specific road durability criteria established for large infrastructure projects.

Industry compliance standards

• ASTM D6373 (Standard Specification for Performance Graded Asphalt Binder)
• EN 14023 (European SBS Polymer Modified Bitumen Specification)
• AASHTO M320 (Performance-Graded Asphalt Binder)
• CE Marking performance for road construction within EU

Typical usage ratio

• 3–5% by weight of total asphalt binder; dosage is adjusted according to climate zone, aggregate composition, and intended pavement thickness to balance elasticity and cost efficiency.

Downstream process integration

• SBS YH-791H is directly introduced into high-shear blending units during bitumen modification. Formulators premix with pre-heated bitumen at proprietary temperature profiles, followed by dynamic mixing and line filtration prior to hot-mix asphalt batching.

Final product types

• Polymer modified asphalt for highways, airport runways, urban roadways, and industrial site pavements.

2. Footwear Outsoles and Midsoles

Footwear compounders select SBS YH-791H to manufacture outsoles and midsoles for sport, leisure, and safety shoes, prioritizing abrasion resistance, cushioning, and slip properties. This raw material allows precise control of durometer and mechanical stability throughout repeated flex cycles, aligning with international product durability norms and footwear material certifications.

Industry compliance standards

• EN ISO 20345:2011 (Safety Footwear)
• REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) compliance for restricted substances
• GB/T 3903.6-2005 (Testing Method for Shoes – Abrasion Resistance)
• CPSIA (Consumer Product Safety Improvement Act) for children’s shoes sold in North America

Typical usage ratio

• 25–45% by total outsole or midsole compound weight; the exact amount is determined based on plasticizer, oil, and filler ratios required for end-use durometer and colorability.

Downstream process integration

• The material is introduced during the compounding stage of injection or compression molding. Blending occurs alongside mineral fillers, plasticizers, and process oils to achieve specific flow and processing indexes for shoe sole production lines.

Final product types

• Non-marking sports outsoles, safety work boot soles, waterproof leisure soles, anti-slip children’s shoe components.

3. Waterproofing Membranes for Construction

Producers of construction-grade waterproof membranes use SBS YH-791H for its high elasticity, low-temperature flexibility, and strong adhesion to mineral substrates. The material ensures membranes retain mechanical performance through long-term thermal cycling, maintaining compliance with roof, bridge, and foundation standards across diverse climates.

Industry compliance standards

• EN 13707 (Reinforced Bitumen Sheets for Roof Waterproofing)
• ASTM D6164 (Standard Specification for SBS-Modified Bituminous Sheet Materials)
• GB 18242-2008 (Elastomeric Modified Bitumen Sheets - Chinese Standard)
• LEED v4 MR (Material Resources credits for low-VOC products in green buildings)

Typical usage ratio

• 8–18% in bituminous membrane formulation; ratio shifts according to membrane thickness, reinforcement type (polyester or glass fiber), and targeted elongation/fatigue resistance.

Downstream process integration

• The polymer is stage-blended with bitumen and mineral stabilizers prior to calendering. The molten compound is applied to carriers using roll-coating or extrusion lines, finishing with sand or foil surfacing before reel cutting.

Final product types

• Roll waterproofing membranes for roofing, tunnels, bridge decks, and basements.

4. Hot Melt Pressure Sensitive Adhesives (HMPSA)

Our SBS YH-791H features controlled molecular weight and block ratio that meet exactly the melt viscosity and tackiness needed for pressure sensitive adhesives. This raw material underpins the base elastomer in HMPSA formulations for tapes, labels, and industrial assembly, supporting compliance with worldwide chemical, packaging, and consumer goods directives.

Industry compliance standards

• FDA 21 CFR 175.105 (Adhesives for Indirect Food Contact)
• EN 923 (Adhesives – Terms and Definitions) and EN 12004 (Adhesives for Tiles – Requirements)
• RoHS (Restriction of Hazardous Substances Directive)
• ISO 9001:2015 (integrated for adhesive QC and traceability)

Typical usage ratio

• 25–40% in base HMPSA formulation; adjusted for required peel strength, shear resistance, and flow by modifying the proportion of tackifiers, plasticizers, and resins.

Downstream process integration

• Introduced to molten blend mixing during adhesive manufacturing. The polymer stage-disperses with tackifier resins and process oils in ribbon blenders prior to slot die or spray application on continuous web lines.

Final product types

• Pressure sensitive packaging tapes, self-adhesive labels, medical plasters, industrial assembly tapes.

5. Thermoplastic Elastomer Compounds for Toy Manufacturing

OEM producers in the toys sector utilize SBS YH-791H as a prime elastomer matrix for soft-touch, safe, and color-stable toys. This grade’s molecular uniformity enables tight control over transparency, tensile elongation, and processability, fulfilling international safety and EU chemical exposure standards for end-consumer goods.

Industry compliance standards

• EN 71-3 (Migration of Certain Elements in Toys)
• ASTM F963 (Standard Consumer Safety Specification for Toy Safety)
• CPSIA Section 108 (Phthalates in children’s products)
• ISO 8124-3 (Safety of Toys – Migration of Certain Elements)

Typical usage ratio

• 30–60% in masterbatch compound depending on required softness, pigment dispersion, and use of mineral or oil extenders for cost management.

Downstream process integration

• Feeds directly into twin-screw extrusion or injection molding, with colorant pre-blending and automatic feeding of softening agents to guarantee uniform dispersion and consistent tactile properties in molded toy parts.

Final product types

• Flexible toy components, soft-grip handles for children’s products, overmolded parts for infant care goods.
