Product Title: B1 NBR-PVC Rubber Foam Sheet

We are thrilled to introduce our premier range of Rubber Foam Products:

1. Product Overview

Rubber foam, a remarkable material foamed from rubber and various additives, showcases exceptional sound insulation, shock absorption, and thermal insulation properties. Based on material classification, rubber foam includes types like natural rubber, synthetic rubber, butyl rubber, neoprene, and silicone rubber. Among these, synthetic rubber and butyl rubber stand out as the most commonly used foam rubbers due to their superior properties.

2. Product Features

Sound Insulation & Shock Absorption: Boasting superior sound insulation and shock absorption, rubber foam significantly reduces noise and vibration impact on the surrounding environment.
Excellent Insulation: With extraordinary insulation capabilities, rubber foam serves as an ideal insulation material for electronic, electrical, and various other equipment.
Lightweight: Compared to similar materials, rubber foam is notably lightweight and resistant to cracking and fracturing, offering enhanced durability.
Low Thermal Conductivity: Featuring low thermal conductivity, rubber foam is perfect for thermal insulation in buildings, railways, and highways, contributing to sound insulation and noise reduction.
Aging Resistance: Exhibiting excellent aging resistance, rubber foam maintains its performance stability over prolonged periods.

3. Manufacturing Process

The production of rubber foam includes key steps such as material proportioning, mixing, foaming, and curing. Initially, rubber raw materials are blended with additives in precise proportions and mixed thoroughly using an internal mixer. The mixture is then foamed in a foaming machine, where the rubber reacts with foaming agents to generate numerous bubbles, forming the foam rubber structure. Finally, curing treatment enhances the elasticity and stability of the foam rubber.

4. Application Scenarios

Rubber foam finds extensive applications across various domains, including but not limited to the following:

Construction: Widely used in building thermal insulation, sound insulation, and noise reduction, rubber foam panels significantly enhance room acoustics and thermal performance.
Transportation: In the automotive industry, rubber foam is employed as shock pads, sealing strips, and tire linings, enhancing vehicle comfort and safety. Additionally, in railway and highway construction, rubber foam panels are used to mitigate traffic noise, ensuring a quieter environment.
Electronics: Thanks to its excellent insulation properties, rubber foam is an ideal choice for insulating electronic and electrical equipment.
Aviation: Given its lightweight, sound insulation, and shock absorption qualities, rubber foam is extensively used in aviation, including aircraft interiors and sound insulation materials.

5. Main Control Parameters

Key control parameters for rubber foam products (such as PVC, NBR) encompass insulation thickness, thermal conductivity, density, combustion performance, vacuum water absorption, dimensional stability, tear strength, compression resilience, and aging resistance. Proper selection and management of these parameters are crucial for ensuring the optimal performance and quality of rubber foam products.

In summary, rubber foam stands out as a high-performance material with extensive applications in construction, transportation, electronics, and aviation. With continuous technological advancements and increasing market demand, the performance and quality of rubber foam products are poised for further enhancement and optimization.
