TPR and PVC are both thermoplastic materials, but they are used for different reasons. TPR, or thermoplastic rubber, is valued for flexibility, elasticity, grip, and soft-touch performance. PVC, or polyvinyl chloride, is valued for chemical resistance, durability, moisture resistance, and cost-effectiveness.
The main difference is that TPR behaves more like rubber, while PVC behaves more like a versatile plastic that can be rigid or flexible depending on its formulation. TPR is commonly used in shoe soles, grips, seals, and soft-touch products. PVC is widely used in pipes, fittings, cable insulation, flexible tubing, films, flooring, roofing, packaging, and waterproofing membranes.

What Is TPR?
TPR stands for thermoplastic rubber. It is a synthetic elastomer that combines rubber-like flexibility with the processing advantages of thermoplastics. This means TPR can soften when heated, flow into a mold, and be reshaped without the permanent chemical changes associated with traditional thermoset rubber.
TPR is commonly used when a part needs to be:
- Flexible
- Durable
- Slip resistant
- Soft to the touch
- Easy to mold into complex shapes
- Suitable for overmolding or grip surfaces
Typical TPR applications include shoe soles, soft grips, handles, seals, gaskets, toys, and other parts where elasticity and tactile feel matter.
What Is PVC?
PVC stands for polyvinyl chloride. It is a widely used engineering thermoplastic known for moisture resistance, UV resistance, chemical resistance, abrasion resistance, and versatility. PVC is available in two main forms: rigid PVC, often called uPVC or PVC-U, and flexible PVC, also called plasticized PVC or PVC-P.
Rigid PVC is commonly used for:
- Pipes
- Fittings
- Profiles
- Construction materials
Flexible PVC is commonly used for:
- Cable insulation
- Flexible tubing
- Hoses
- Protective equipment
- Films
- Flooring
- Roofing
- Waterproofing membranes
- Packaging
PVC can be processed using extrusion, injection molding, and blow molding. PVC pipes and fittings can also be bonded using adhesives.
Main Difference Between TPR and PVC
The main difference between TPR and PVC is elasticity versus structural versatility.
TPR is designed to feel and perform like rubber. It is flexible, elastic, and well suited for soft-touch or high-grip parts. PVC is more versatile in stiffness: it can be rigid for construction products or flexible for cables, hoses, and films.
Choose TPR when the product needs softness, stretch, grip, or energy absorption. Choose PVC when the product needs chemical resistance, dimensional stability, durability, or lower material cost.
TPR vs PVC Properties
| Property | TPR | Flexible PVC | Rigid PVC |
|---|---|---|---|
| Tensile strength | Around 2.5 MPa | Around 9.65 MPa | Around 16.6 MPa |
| Melting temperature range | 140–185°C | Around 190°C | Around 177°C |
| Hardness | Around 40 Shore A | Around 75 Shore A | Around 68.3 Shore D |
| Elongation at break | Around 550% | Around 328% | Around 312% |
| Tear resistance | Around 15 N/mm | Around 53.7 N/mm | Around 33.6 N/mm |
| Dielectric strength | Not specified | Around 58.9 kV/mm | Around 14–20 kV/mm |
These values should be treated as general reference points because both TPR and PVC are available in many formulations. For production parts, always check the specific supplier datasheet for the exact grade being used.
TPR Applications
TPR is best suited to applications that need a flexible, soft, rubber-like material. Common uses include:
- Shoe soles
- Soft-touch handles
- Grips
- Dog toys
- Tire treads
- Gaskets
- Seals
- Overmolded components
- Anti-slip surfaces
TPR is especially useful when a product needs both flexibility and thermoplastic processing.
PVC Applications
PVC is used across construction, electrical, industrial, packaging, and consumer products. Common uses include:
- Rigid pipes
- Pipe fittings
- Cable insulation
- Flexible tubing
- Hoses
- Tank liners
- PVC films
- Flooring
- Roofing
- Waterproofing membranes
- Packaging
PVC is often chosen when chemical resistance, moisture resistance, durability, and cost control are important.
TPR vs PVC Cost
PVC is generally less expensive than TPR. The main reason is scale: PVC is produced in very large global volumes, which helps reduce its cost. TPR is usually more expensive because it requires more complex elastomeric formulations to deliver rubber-like flexibility and grip.
As a general guide, PVC can reach around $1,389 per metric ton, while TPR commonly falls around $1,470 to $2,250 per metric ton, although actual pricing varies by formulation, supplier, market demand, and processing requirements.
Cost takeaway: choose PVC for lower-cost, high-volume applications unless the part specifically needs the elasticity, softness, or grip of TPR.
Is TPR More Flexible Than PVC?
Yes. TPR is typically more flexible and elastic than PVC. TPR is designed to behave like rubber, while PVC’s flexibility depends on whether it is plasticized. Flexible PVC can bend and deform, but TPR generally provides a softer feel, higher elongation, and better rubber-like recovery.
Is PVC Stronger Than TPR?
In many applications, PVC can offer higher tensile strength and tear resistance than TPR, especially rigid PVC. The source comparison lists tensile strength values of about 2.5 MPa for TPR, 9.65 MPa for flexible PVC, and 16.6 MPa for rigid PVC.
However, “stronger” depends on the requirement. TPR may be better for repeated flexing, grip, or soft impact absorption, while PVC may be better for rigid structural use, chemical exposure, or lower-cost durability.
Recyclability and Sustainability
Both TPR and PVC are thermoplastics, so both can theoretically be recycled. However, real-world recycling depends on local infrastructure, material purity, additives, and economic demand.
PVC can be recycled multiple times, but many plastic products still end up in landfill or the environment. TPR can also be recycled in theory, but because it is used in lower volumes than major commodity plastics, recycling may be less common or less economical.
Sustainability takeaway: neither material should automatically be considered sustainable. For eco-conscious designs, evaluate recycled-content grades, supplier take-back programs, material separation, and alternative polymers.
Alternatives to TPR and PVC
Possible alternatives to TPR and flexible PVC include:
- TPE-S / SEBS: flexible thermoplastic elastomer with rubber-like properties
- TPU: thermoplastic polyurethane with good toughness and elasticity
Possible alternatives to rigid PVC include:
- Polypropylene, or PP
- HDPE, or high-density polyethylene
These alternatives may offer better toughness, flexibility, chemical resistance, recyclability, or application-specific performance depending on the product.
Which Material Should You Choose?
Choose TPR if you need:
- A soft rubber-like feel
- High flexibility
- Grip or slip resistance
- Elastic recovery
- Soft-touch overmolding
- Comfort in hand-held or wearable products
Choose PVC if you need:
- Lower material cost
- Chemical resistance
- Moisture resistance
- Rigid construction parts
- Flexible tubing or cable insulation
- High-volume industrial or building products
For most soft-touch consumer products, TPR is the stronger choice. For pipes, cables, hoses, films, and construction products, PVC is usually more practical and economical.
