Understanding DRC, MST, and VFA in Latex 60% DRC: A Technical Guide for Quality Buyers

When it comes to natural rubber latex, quality is more than just a label—it’s a set of technical values that directly affect your production line. For quality control managers and sourcing professionals, understanding what’s behind the latex 60% DRC technical specifications helps ensure stability, safety, and efficiency.

In this article, Ngoc Chau Natural Rubber provides a transparent breakdown of key parameters like DRC (Dry Rubber Content), MST (Mechanical Stability Time), and VFA (Volatile Fatty Acid)—all backed by certified test results from our 2025 laboratory analysis.

Why Do DRC, MST, and VFA Matter?

These parameters are the pillars of latex consistency. If you’re producing gloves, dipped threads, foam pads, or adhesives, unstable latex can lead to:

• Film breakage

• Coagulation in tanks

• Poor shelf life

• Increased rejection rates

With Ngoc Chau Latex 60% DRC, we ensure each parameter is tested and certified before export.

What Is DRC (Dry Rubber Content)?

DRC measures the weight percentage of pure rubber in the latex. A higher DRC means more usable rubber per kilogram—critical for cost control and formulation precision.

📌 Our Test Result:

• DRC: 60.34%

• Standard Limit: ≥ 60.00%

• Test Method: TCVN 4858:2007 / ISO 126:2005

🔍 Why It Matters:

• Guarantees optimal yield per batch

• Improves performance in coating and dipping

• Keeps latex viscosity within operational tolerance

What Is MST (Mechanical Stability Time)?

MST reflects how resistant latex is to mechanical shear—such as mixing, pumping, or dipping. A higher MST ensures that latex won’t break down prematurely in your processing equipment.

📌 Our Test Result:

• MST: 862 seconds

• Standard Limit: ≥ 650 seconds

• Test Method: TCVN 6316:2007 / ISO 35:2004

🔍 Why It Matters:

• Reduces risk of coagulation during production

• Enhances line stability in high-speed systems

• Improves compatibility with surfactants and additives

What Is VFA (Volatile Fatty Acid)?

VFA indicates the presence of bacterial degradation products. It directly correlates with latex odor, cleanliness, and shelf life.

📌 Our Test Result:

• VFA: 0.033

• Standard Limit: ≤ 0.06

• Test Method: TCVN 6321:1997 / ISO 506:1992

🔍 Why It Matters:

• Low VFA = longer storage, fewer odor complaints

• Critical for medical and skin-contact applications

• Sign of clean production and preservation techniques

Frequently Asked Questions

Q1: Can I request a third-party lab result?
Yes. We support SGS, Quatest, or your own inspection agency.

Q2: Is MST always tested before shipping?
Yes. MST is checked per batch and marked on the COA.

Q3: Is VFA important for non-medical latex use?
Still relevant—it affects odor, shelf life, and bacterial resistance.

Q4: What’s the difference between DRC and TSC?
TSC = total solids (rubber + others), DRC = pure rubber.

Q5: Do you follow ISO or local standards?
Both. All TCVN methods are equivalent to ISO standards.

Conclusion: Choose Latex That’s Measured, Not Assumed

When you’re sourcing latex for performance-critical goods, you can’t rely on assumptions. You need tested, certified, and consistent latex. That’s what Ngoc Chau Natural Rubber delivers.

With:

• Verified DRC ≥ 60%
