Tensile Strength Ranking of Elastic Resins & Rubbers

What is Tensile Strength (MPa)?

Tensile strength refers to the maximum stress a material can withstand when pulled before it ruptures or breaks. This fundamental mechanical property indicates a material's load-bearing capacity and serves as a crucial metric in material selection and product design. Materials with higher tensile strength offer significant advantages as they can withstand greater loads and are less prone to fracture, thereby enhancing safety in applications and allowing for weight reduction in mechanical components and structural materials. When selecting materials, it is important to balance tensile strength with other factors such as ductility and elongation properties, cost considerations, and processing complexity.

Tensile Strength Ranking of Elastic Resins & Rubbers（Ranked by tensile strength, limited to materials with elongation of 100% or more）

Rank	Material/Classification	Tensile Strength (MPa approx.)	Elongation at Break (% approx.)	Characteristics and Applications
1	TPU (Thermoplastic Polyurethane) a type of TPE	20～50 MPa	400～800%	Polyurethane elastomer. Excellent balance of abrasion resistance, oil resistance, elasticity, and mechanical strength. Commonly used in applications requiring high elasticity and strength, such as shoe soles, casters, tubing, and protective covers.
2	TPE-S (TPS) Styrenic Thermoplastic Elastomer SBS, SEBS, etc.	5～40 MPa	400～1,000%	Styrenic block copolymer. Widely used for grip materials, seals, sporting goods, etc. Highly flexible and stretchable, though typically with lower heat and oil resistance compared to other TPEs.
3	TPU (Thermoplastic Polyurethane) a type of TPE	10～30 MPa	500～900%	Known for its high natural elasticity. Widely used in tires, vibration-dampening components, rollers, etc. Weather resistance and oil resistance are typically enhanced through compounding with fillers and additives.
4	BR (Butadiene Rubber) Thermosetting Rubber	10～30 MPa	500～1,000%	Notable for exceptional elongation and high elasticity among rubber materials. Frequently used in applications requiring shock absorption such as tires, shoe soles, and belts. Strength and weather resistance can be tailored using reinforcing materials like carbon black.
5	TPO (Thermoplastic Polyolefin) a type of TPE, PP+EPDM, etc.	10～30 MPa	200～700%	A blend or copolymer primarily composed of polypropylene (PP) and EPDM rubber. Suitable for large molded products including automotive bumpers, exterior components, and appliance housings. Combines lightweight properties with excellent weather and impact resistance.
6	RLR（Rubber-Like Resin）	6～30 MPa	300～1,000%	Offers a combination of softness and stretchability with impressive toughness. Highly resilient - resistant to puncturing even when pierced with a screwdriver. Features excellent scratch resistance and shock-absorbing properties.
7	SBR (Styrene-Butadiene Rubber) Thermosetting Rubber	10～25 MPa	300～600%	The second most commonly used synthetic rubber after Natural Rubber. Used in applications requiring wear resistance and elasticity such as tires and belts. Often blended with Natural Rubber to enhance performance characteristics.
8	EPDM (Ethylene-Propylene Rubber) Thermosetting Rubber, raw material for TPO/TPV	10～25 MPa	300～600%	Excellent weather and ozone resistance, widely used in outdoor applications and automotive weather strips. Also serves as a base material for TPO and TPV. Properties can be customized through cross-linking and various compounding agents.
9	NBR (Nitrile Rubber) Thermosetting Rubber	10～25 MPa	200～500%	Superior oil and chemical resistance, primarily used in industrial applications such as gaskets, seals, and hoses. Both elongation and strength characteristics can be significantly modified through compounding with reinforcing materials and plasticizers.
10	Silicone Rubber (Q) Thermosetting Rubber	5～15 MPa	200～700%	Exceptional heat, cold, and weather resistance; utilized across diverse sectors including medical, food, and electrical components. While relatively lower in strength compared to other rubbers, it can be enhanced through silica reinforcement or modification.

RLR (Rubber-Like Resin): A Revolutionary Material Combining High Tensile Strength and Elongation

Traditional resin materials have struggled to balance flexibility and durability. To overcome this challenge, we've developed Rubber-Like Resin (RLR), which combines rubber-like flexibility with exceptional durability.

This innovative material features superior elasticity and scratch resistance, while also providing excellent vibration absorption and chemical resistance. Since it cures at room temperature, no heating furnace is required—contributing to energy efficiency. RLR can be utilized across diverse applications, from electronic component coatings to construction materials and automotive parts.
