Platinum Cured High Temperature Silicone Rubber HTV Compound with 300 °C Continuous Service and Shore A 50 for Molded Parts

Product Description:

5032HT is a platinum-cured HTV silicone compound rated for continuous service up to 300 °C. This advanced elastomer exhibits exceptional thermal stability, making it an ideal choice for environments where high temperatures are a constant challenge. It is supplied uncured as a solid compound, so it can be compression moulded, transfer moulded or extruded. The platinum system leaves no peroxide breakdown products, which keeps odour and volatile content low in closed assemblies.

One of the key attributes of this High Temperature Silicone Elastomer is its carefully controlled density of 1.15 G/cm³. This density contributes to the material’s robust mechanical properties, providing an optimal balance between flexibility and strength. The elastomer’s tensile strength reaches up to 9 MPa, demonstrating its superior ability to withstand mechanical stresses without compromising its structural integrity. Such strength makes it suitable for seals, gaskets, and other components that require both high thermal resistance and mechanical durability.

In terms of storage and handling, the High Temperature Silicone Elastomer requires a cool, dry, and well-ventilated place, away from direct sunlight. Proper storage conditions are essential to preserve the material’s quality and extend its usability. When stored correctly, this silicone rubber has a shelf life of 6 months at 25 °C, ensuring that it remains ready for use without degradation over time. This feature is particularly beneficial for manufacturers and users who rely on maintaining inventory without sacrificing performance.

Another notable aspect of this High Temperature Silicone Elastomer is its availability for OEM and ODM services. This flexibility allows customers to customize the product to their specific needs, whether it involves tailoring the formulation, dimensions, or other properties. The manufacturer’s commitment to OEM/ODM service ensures that clients receive a product perfectly aligned with their application requirements, enhancing efficiency and effectiveness in their end products.

The High Temperature Silicone Elastomer is widely used in industries such as automotive, aerospace, electronics, and manufacturing, where materials are frequently exposed to temperatures that would degrade conventional rubbers. It is used where conventional rubbers degrade: automotive engine-bay seals, oven and heater gaskets, heat pads and industrial moulded parts that run at sustained high temperature. Resistance to thermal ageing and oxidation keeps sealing force stable over long service life.

In summary, 5032HT is a platinum-cured Shore A 50 compound rated for continuous service up to 300 °C, with 9 MPa tensile, 600% elongation and 15 kN/m tear. It suits moulded seals, gaskets and pads that sit at sustained high temperature rather than only seeing short spikes.

Applications:

The RUIHE 5032HT High Temperature Silicone Rubber is a premium High Temperature Silicone Elastomer designed to meet the demanding needs of industries requiring materials that can withstand extreme conditions. Originating from Guangzhou, Guangdong, China, this product boasts certifications including RoHS, REACH, and ISO 9001, ensuring its quality and compliance with international standards. Its uncured solid silicone compound form allows for versatile processing and molding applications, making it ideal for a wide range of high-temperature environments.

In automotive parts it is used for gaskets, seals and hoses that sit close to the engine and see sustained heat.  At Shore A 50 with 9 MPa tensile and 600% elongation, the compound keeps sealing force and follows flange movement through thermal cycling instead of taking a permanent set. Its remarkable elongation at break of 600% ensures durability and flexibility, critical for parts subjected to constant movement and thermal cycling.

In electronics it is used for heat-resistant pads and protective components that shield sensitive parts from short heat exposure. This grade is not specified for electrical insulation duty, so where the part must carry a dielectric requirement, tell us at enquiry stage and we will quote a grade with electrical data.

Additionally, the RUIHE 5032HT is widely used in industrial manufacturing scenarios such as molding and casting of silicone parts that require outstanding thermal stability. Its uncured solid form facilitates ease of use in injection molding and extrusion processes. Packaging details include 20 Kg per carton with an inner PE bag to preserve material quality during storage and transport. With a minimum order quantity of 20 Kg and a delivery time of 7-15 working days, it is accessible for both small-scale and large-scale production needs. Payment terms are flexible with T/T, requiring a 30% deposit before production and balance payment before shipment.

Overall, the RUIHE 5032HT High Temperature Silicone Elastomer is perfectly suited for applications where high heat resistance, mechanical robustness, and flexibility are essential. From automotive parts and electronic insulation to industrial molds and components exposed to extreme temperatures, this silicone rubber product delivers reliable performance and longevity, making it a valuable material across multiple sectors.

We also offer customized packaging solutions upon request to meet specific customer requirements. Our goal is to ensure that your High Temperature Silicone Rubber products arrive safely and in optimal condition, ready for use.

FAQ:

Q1: What is the brand and model number of this High Temperature Silicone Rubber?

A1: The High Temperature Silicone Rubber is branded RUIHE with the model number 5032HT.

Q2: Where is the High Temperature Silicone Rubber manufactured?

A2: This product is made in Guangzhou, Guangdong, China.

Q3: What certifications does the RUIHE 5032HT High Temperature Silicone Rubber have?

A3: It is certified with RoHS, REACH, and ISO 9001 standards.

Q4: What is the minimum order quantity and packaging details for this product?

A4: The minimum order quantity is 20 Kg. It is packaged in 20 Kg per carton with an inner PE bag for protection.

Q5: What are the delivery time and payment terms for ordering this silicone rubber?

A5: The delivery time ranges from 7 to 15 working days. Payment terms are T/T with a 30% deposit before production and the balance paid before shipment.

Q6: Is 5032HT peroxide-cured or platinum-cured?

A6: It is platinum-cured. The addition-cure system leaves no peroxide breakdown products, so odour and volatile content stay low — which matters for closed assemblies and for parts packed soon after demoulding.

Q7: What is the continuous service temperature?

A7: 300 °C. The compound is rated for continuous service at this temperature, not only for short excursions, so it suits parts that sit in sustained heat. Tell us the duty cycle and we will confirm the grade.
