[Free Sample Gift] Comparison of Rubber Sponges: NR, NBR, CR, EPDM

Various types of rubber-based sponges, commonly known as rubber sponges, have been categorized by their applications, usage environments, and excellent performance (strength, waterproofing, heat resistance, chemical resistance, etc.).

NR Series (Natural Rubber) Rubber Sponge - Characteristics Possesses the most rubber-like elasticity. Good mechanical strength and abrasion resistance. Weak against heat and ultraviolet rays. - Main Applications Various tires, footwear, hoses, belts, vibration-damping rubber, industrial gaskets, etc. NBR Series (Nitrile Rubber) - Characteristics Oil resistance is the main feature. Excellent gas permeability resistance. Poor weather resistance and cold resistance. - Main Applications Oil seals, gaskets, packing, oil-resistant hoses, etc. CR Series (Chloroprene Rubber) - Characteristics Has average properties such as weather resistance, oil resistance, and heat resistance. Excellent flame retardancy. - Main Applications Wire insulation, automotive parts, belts and hoses, window frame rubber, adhesives, etc. SR Series (Silicone Rubber) - Characteristics High heat resistance, cold resistance, and weather resistance. Excellent electrical properties and non-stick properties. Material is physiologically safe. Mechanical strength is inferior. - Main Applications Food-related, medical device-related packing, gaskets, industrial rolls, etc. EPDM Series (Ethylene Propylene Rubber) - Characteristics Excellent ozone resistance, weather resistance, chemical resistance, heat resistance, and cold resistance. - Main Applications Window frames, automotive parts, electrical wires, outdoor cushioning materials, shock-absorbing rubber materials, etc.

• Rubber sheet

The characteristic feature is that the natural wood grain texture appears no matter where it is cut. It reproduces the wood grain through a special manufacturing method, and no two pieces are the same.

The wood grain sponge TW-65 is an EVA sponge. It has good cushioning properties and a soft feel, making it versatile for use in cushions, flooring (mats), and novelties. We welcome inquiries not only for raw material sales but also for processing into desired shapes.

• Wood-based board

Mix materials like foam boards with original color combinations and heat press them! No two patterns are the same!

Features - ✨Vibrant colors with beautiful combinations✨ - ✨Excellent processability such as cutting, extracting, shaving, and bonding✨ - Lightweight - Cushioned - Floats in water and does not absorb moisture - Excellent thermal insulation and heat retention - Highly resistant to chemicals, especially strong against acids and alkalis ↓A one-of-a-kind puzzle that stimulates your imagination: 'PM6 Polymorock' Puzzle Sponge Pieces 24 pieces https://item.rakuten.co.jp/spongeland/10000159/?iasid=07rpp_10095___ed-kg0hw6he-2kksr-65856f99-afde-4dc4-ab25-32498fcc2cb3

Are you making progress on measures for the "2024 Problem"? The management of drivers' working hours is becoming stricter, and in the logistics field, reducing "waiting time for loading" has become an urgent issue. To address this challenge, our company, Hotron, proposes the "Vehicle Detection Ultrasonic Sensor 'HM-UX2'," which instantly grasps the availability of loading bays. The 'HM-UX2' contributes to the resolution of waiting times by accurately understanding the availability status, reducing unnecessary waiting and queuing, and shortening waiting times, thereby alleviating the burden on drivers! By replacing the "eyes" of your loading bay management with this high-precision sensor, why not start taking measures against the "2024 Problem"? Take a look at the product features: "Can it accurately detect availability?" "Can we really use it in our company?" "I just want to know the cost, even if it's an estimate." If you have any questions or requests, please feel free to consult us first.
