Measurement System

Prefix M: SI Metric Units

Specifies that tensile strength is expressed in MegaPascals (MPa), temperatures in Celsius (°C), and dimensions in millimeters. Omission of 'M' indicates Imperial units (PSI, °F).

Base Polymer Chemistry

Type & Class: BG (Nitrile NBR)

Type B: Heat resistance up to 100°C continuous.
Class G: Maximum volume swell ≤ 40% in ASTM No. 3 Oil. Unambiguously identifies a medium-high ACN Nitrile elastomer.

Physical Properties

714: 70A Durometer • 14 MPa

7: 70 ± 5 Shore A durometer hardness.
14: Minimum ultimate tensile strength of 14 MPa (approx. 2,030 PSI) with minimum 250% elongation at break.

Specific Test Suffixes

Suffix Requirements

B14: Compression set max 25% (22h @ 100°C).
EA14: Water immersion volume change ±5%.
EF11: Fuel immersion swell resistance.
EO14: ASTM No. 1 Oil immersion testing.

Application Data Checklist

What Material Engineers Need to Specify a Compound

A polymer name alone is never sufficient for precision manufacturing. Provide these four operational parameters so our laboratory can formulate the optimal compound formulation and mold tooling.

01

Media & Fluid Exposure

Specify every contacting fluid, fuel, lubricant, cleaning solvent, or refrigerant gas — including concentration percentages, additives, and whether immersion is continuous or intermittent.

02

Thermal Operating Profile

Define continuous normal operating temperature, cold-start ambient minimums, peak thermal spikes, duration at extremes, and expected thermal cycling frequency.

03

Mechanical Duty & Pressure

Detail static clamping force or dynamic motion (reciprocating/rotary), surface finish Ra, working pressure or vacuum, vibration frequency, and maximum allowable compression set.

04

Standards & Validation

State required ASTM D2000, SAE J200, DIN ISO 3601, or OEM internal specifications, PPAP Level (1–3), FAIR dimensional inspection, and material test certificates (MTC 3.1).

In-House Testing & Compound Qualification Lab

Every custom formulation is verified in our Gurugram testing lab using computerized Moving Die Rheometers (MDR), Universal Tensile Testers (UTM), cryogenic embrittlement baths, and optical video metrology.
