Custom Neoprene Rubber Manufacturer | Sheets, Seals & Extrusions Subtitle: High-Performance CR Material Direct from the Factory – Stop Overpaying Distributors.
Partner with a Direct Source Searching for reliable neoprene rubber manufacturers can be frustrating when most suppliers are just middlemen. At RiseUp Rubber, we are different. We operate our own mixing, molding, and extrusion lines, giving you full control over material hardness, dimensions, and costs.
What is Neoprene Rubber? Is neoprene rubber the right choice for your project? Technically known as Chloroprene (CR), it is the industry’s most versatile “all-purpose” elastomer.
The Balance: It offers a unique balance of resistance to oil, chemicals, sunlight, and weathering that no other single material can match.
Our Capability: Unlike standard neoprene manufacturers who only sell stock sheets, we customize compounds to meet specific tensile strengths and fire-retardant standards (UL94).
Engineering Properties: The "Jack of All Trades" Elastomer
Why Engineers Choose Neoprene When specific operating conditions are unknown or vary, Neoprene is the safest bet. Among its key neoprene properties, its ability to resist flex-cracking and bond well to metals makes it unique. It stands up to:
Moderate Chemicals: Good resistance to oils, greases, and mild acids.
Outdoor Elements: Excellent resistance to ozone, oxidation, and sunlight aging.
Physical Toughness: High tensile strength and abrasion resistance.
The Truth About Neoprene Melting Temperature A frequent question we receive is: “What is the neoprene melting temperature?” Here is the engineering reality: Is neoprene rubber thermoplastic? No, it is a thermoset material. Once vulcanized, Neoprene does not melt.
Thermal Behavior: Instead of melting like plastic, it remains stable up to its maximum operating limit (approx. +120°C). Above this, it will eventually char or degrade, but it will not turn into a liquid. This characteristic is crucial for applications requiring fire retardancy.
Neoprene Gasket Specification Chart We custom compound to your exact specs. Below are typical values for our industrial grades:
| Property | Standard Range | Custom Capability |
| Hardness (Shore A) | 40 – 70 Duro | 30 (Soft) – 90 (Hard) |
| Working Temperature | -40°C to +100°C | Up to +120°C (Heat Stabilized) |
| Tensile Strength | 5 – 10 MPa | Up to 20 MPa (High Grade) |
| Color | Black | Grey, Red, or Custom Colors |
Manufacturing Capabilities: From Sheets to Complex Profiles
1. Calendered Rubber Sheets
We manufacture high-quality rubbersheet rolls in various thicknesses (0.5mm to 50mm). Whether you need commercial-grade material for flooring or high-grade neoprene gasket material for die-cutting, we control the surface finish (smooth or fabric impression) to ensure easy processing.
2. Custom Extrusion Profiles Need a continuous seal?
Our extrusion lines produce custom neoprene seal profiles tailored to your CAD drawings.
• Common Applications: We frequently produce U-channels, D-strips, and complex neoprene door gasket profiles for shipping containers and electrical enclosures.
• Advantage: We create the tooling in-house, significantly reducing lead times for custom shapes.
3. Precision Molded Parts
For critical sealing, we offer compression and injection molding.
• O-Rings: We mold standard and custom neoprene o rings with tight tolerances, ideal for refrigerant systems (HVAC) where FKM is overkill and NBR fails due to ozone.
• Custom Shapes: From bellows to vibration mounts, our engineering team assists with part design to optimize moldability and performance.
Material Selection: Why Choose Neoprene?
The “Middle Ground” Advantage
In the rubber industry, Neoprene is known as the “general-purpose warrior.” Its primary advantage lies in its balance.
• Vs. Nitrile (NBR): NBR has superior fuel resistance but cracks quickly under sunlight (UV) and ozone.
• Vs. EPDM: EPDM has superior weather resistance but swells instantly if touched by oil or grease.
• The Neoprene Solution: If your application involves outdoor exposure and incidental oil contact, Neoprene is the scientifically correct choice.
Common Neoprene Rubber Uses Due to this unique versatility, neoprene rubber uses span across diverse industries where mixed environmental factors exist:
• HVAC & Construction: Window seals and neoprene gaskets for air conditioning units that face both UV rays and compressor lubricants.
• Automotive: CV joint boots, suspension bushings, and hose covers that must endure road grease and weather.
• Marine & Industrial: Dock bumpers and neoprene gasketing for water-tight hatches, providing excellent resistance to salt water and oxidation.

Frequently Asked Questions about Neoprene (CR)
Q: How do I define the right material for my order?
A: To get an accurate quote, please provide the neoprene gasket specification including:
1. Hardness: Standard is 60 or 70 Shore A (Durometer).
2. Dimensions: Thickness, Width, and Length (or a CAD drawing).
3. Grade: Commercial Grade, High-Grade (High Tensile), or Flame Retardant.
Q: Do you ship “Neopreen” rubber to Europe?
A: Yes. We notice many inquiries from the Netherlands and Germany using the spelling “neopreen rubber”. As a global neoprene rubber manufacturer, we ship our custom sheets and molded parts worldwide, including DDP (Delivered Duty Paid) options to Europe and North America.
Q: Is Neoprene flame retardant?
A: Yes, naturally. Because it contains Chlorine, Neoprene is self-extinguishing and resists burning better than hydrocarbon rubbers like Natural Rubber or EPDM. We can also custom compound materials to meet strict UL94 V-0 flame retardant standards for electrical enclosures.
Q: Can you apply adhesive backing to sheets and strips?
A: Absolutely. We can laminate high-strength PSA (Pressure Sensitive Adhesive) backing to any rubbersheet or extruded strip, making installation “peel-and-stick” easy for your assembly team.
