CORE TECHNICAL SPECIFICATIONS

1. Material Composition & Compound Engineering

RUBBER-KU Rubber Mounting Blocks are formulated using high-performance elastomers:

• Natural Rubber (NR) → High elasticity, superior damping
• Nitrile Rubber (NBR) → Oil and fuel resistance
• EPDM Rubber → UV, ozone, and weather resistance
• Neoprene (CR) → Balanced mechanical + chemical stability

Compound Enhancements:

• Carbon black reinforcement (tensile strength)
• Anti-oxidants & anti-ozonants (aging resistance)
• Plasticizers (flexibility tuning)
• Crosslinking systems (sulfur / peroxide curing)

---

2. Mechanical Properties

Hardness (Shore A)

• Range: 40 – 80 Shore A
• Tolerance: ±5 Shore A

Tensile Strength

• Typical: 8 – 20 MPa (depending on compound)

Elongation at Break

• Range: 250% – 600%

Tear Resistance

• High resistance to crack propagation

---

3. Load & Compression Characteristics

Static Load Capacity

• From 50 kg to several tons per block

Compression Deflection

• Recommended working deflection: 5% – 15% of height

Compression Set

• Typically < 25% (ASTM D395 standard)

Creep Resistance

• Low long-term deformation under constant load

---

4. Dynamic Performance Parameters

Natural Frequency Relationship

fn=12πkmf_n = \frac{1}{2\pi}\sqrt{\frac{k}{m}}fn​=2π1​mk​​

Typical Range:

• 5 Hz – 25 Hz depending on stiffness and load

---

Transmissibility Equation

T=1+(2ζr)2(1−r2)2+(2ζr)2T = \sqrt{\frac{1 + (2\zeta r)^2}{(1 - r^2)^2 + (2\zeta r)^2}}T=(1−r2)2+(2ζr)21+(2ζr)2​​

Design Target:

• Isolation efficiency: 80% – 95%

---

Damping Ratio (ζ)

• Typical: 0.05 – 0.20

---

5. Shear & Compression Modulus

Compression Modulus

• Determines load-bearing stiffness

Shear Modulus (G)

• Typical range: 0.5 – 1.5 MPa

Key Insight:

• Shear mode → higher damping
• Compression mode → higher load capacity

---

6. Thermal Properties

Operating Temperature Range

• Standard: -30°C to +100°C
• Custom: up to +120°C

Glass Transition Temperature (Tg)

• Typically -50°C to -70°C (compound dependent)

---

7. Chemical & Environmental Resistance

Oil Resistance (NBR variants)

• Suitable for hydrocarbon exposure

UV & Ozone Resistance (EPDM variants)

• No surface cracking under outdoor exposure

Chemical Resistance

• Resistant to mild acids, alkalis, and industrial fluids

---

8. Dimensional & Design Specifications

Standard Dimensions

• Custom sizes available (length, width, height)

Tolerance

• ±0.5 mm to ±2 mm depending on size

Shape Configurations

• Solid block
• Hollow block
• Ribbed / grooved surface
• Multi-layer composite

---

9. Shape Factor (Critical Design Parameter)

Shape Factor = Loaded Area / Free Area

Engineering Impact:

• High shape factor → increased stiffness
• Low shape factor → improved flexibility

---

10. Fatigue & Lifecycle Performance

Fatigue Resistance

• Designed for millions of load cycles

Aging Resistance

• Minimal property degradation over time

Expected Service Life
