TPE THERMOPLASTIC ELASTOMER

A Thermoplastic Elastomer (TPE) combines the rubber-like properties of a thermoset elastomer and the processing features of a thermoplastic. It is possible because thermoplastic elastomer composed of two phases a soft phase which provides elastic properties, and a hard phase which represents the thermoplastic segment and provide both processing ease and full recyclability to the material. Thermoplastic Elastomers can be molded into the desired shapes by means of the classical processing technologies used for plastic materials the most common are injection moulding, extrusion and blow molding.

Hardness range available from 40 to 95 shore A.
Operating temperature from -40 °C to +50 °C.
High elastic recovery both at low and room temperature.
Excellent price/quality ratio.
Excellent colourability.
Processabilitywithout difficulty.
Lightweight up to 0.50 Specific gravity – Used for footwear application like Shoe Soles, Safety Shoes, Industrial Shoes, Sports Shoes & Automotive Segment

TPO

Thermoplastic Polyolefins (TPO) compounds are polypropylene based materials that have been modified to provide better impact resistance compared to standard off-the-shelf Polypropylene grades.TPO is easily processed by injection molding, profile extrusion, and thermoforming. However, TPO cannot be blown, or sustain a film thickness less than 1/4 mil (about 6 micrometres). It is designed primarily for automotive exterior ornamentation applications requiring low thermal expansion characteristics and a moderate degree of flexibility

CHEMICAL STRUCTURE

TPO thermoplastic elastomer family consists of heterophasic compounds based on an amorphous elastomeric phase and a crystalline phase, usually both of a polyolefinic nature. This chemical composition conferselastic properties to finished products up to temperature of 180°C. These compounds are classified as TPOs.

TPV

Sperene thermoplastic vulcanizates (TPVs) are high-performance elastomers, which offer manufacturing flexibility, durability, and ease of processing. By offering high-up and consistent performance across automotive, industrial and demanding consumer applications, Sperene TPV offers the potential for reduced system costs, recyclability, and reduced weight, compared to materials such as EPDM (ethylene propylene diene polyethylene backbone) or other thermoset rubbers.

CHEMICAL STRUCTURE

TPV is a thermoplastic elastomer and more precisely it is a vulcanized thermoplastic elastomer (TPV). It is made of an elastomeric phase (dynamically vulcanised EPDM) which is deeply dispersed in a polyolefinic thermoplastic matrix, whose combination determines a real plasto-elastomeric alloy characterised by high performances and extremely easy process ability. The thermoplastic matrix allows TPV to be processed in an easy, inexpensive way by means of traditional technologies used for thermoplastic materials and to be fully recyclable, while its elastomeric phase features typically recovery and softness.

“Why TPV is the Future of SWR Sealing Rings: Precision, Durability & Sustainability”

In SWR systems, sealing rings are critical for leak-proof performance.
Traditionally, EPDM or natural rubber ruled the game — but now, TPV (Thermoplastic Vulcanizates) is taking over.
Why TPV?
✔ Rubber-like flexibility + thermoplastic processability
✔ Superior weather & chemical resistance
✔ Recyclable & eco-friendly
✔ Precision moulding for zero-leak joints
✔ Cost-efficient over lifecycle

Key Advantages:
1️⃣ Handles UV, ozone & harsh conditions
2️⃣ Tight dimensional control
3️⃣ Faster, simpler processing
4️⃣ Supports green manufacturing
5️⃣ Lower total system cost

Industry Trend:
Leading global and Indian pipe manufacturers are switching to TPV for SWR rings — driven by automation compatibility, consistent quality, and sustainability goals.

*Ball Valve Seals – Why Material Selection Matters*

Ball valve seals may seem like small components, but they are the first line of defense against leakage in fluid handling systems. A minor seal failure can lead to downtime, inefficiencies, and even safety risks. That’s why choosing the right material is critical.

🔑 Key Roles of Ball Valve Seals
Ensure tight closure under varying pressures & temperatures
Enable smooth operation across industries (water, oil & gas, chemicals, plumbing)
Protect system integrity and reduce costly failures

⚙️ Materials in Focus
Different materials offer different trade-offs:
PTFE – High chemical & temperature resistance, but brittle
FKM (Viton) – Best for hydrocarbons & fuels, but costly
EPDM – Excellent for water & steam, UV/weather resistant
NBR – Affordable & oil resistant, but weak against UV/heat
TPE-S – Cost-effective for moderate temperatures
TPV – Balanced solution: durable, recyclable, versatile across applications

🌟 Why TPV is Emerging as a Go-To Material
Broad chemical compatibility
Works reliably up to ~135°C
Strong aging & UV resistance
Cost-performance advantage
Recyclable & sustainable

📌 Key Takeaway
There is no universal “best” seal material. The right choice depends on balancing temperature, chemical resistance, pressure, and durability. However, TPV has been gaining traction for its ability to perform well across diverse conditions while remaining cost-effective.
