Quality Policy at Astra

At Astra Corporation, quality isn’t a target; it’s a promise and resolve. Our quality policy reflects a deep-rooted commitment to delivering high-performance Butyl Reclaim Rubber that meets and surpasses client expectations. To bring this policy to life, we’ve invested in a state-of-the-art integrated laboratory, a hub for innovation, equipped with cutting-edge testing and research tools. This facility plays a critical role in ensuring that each product we deliver adheres to the highest quality and performance standards.

Our Integrated Laboratory

Our commitment to producing the highest quality Butyl Reclaim Rubber is backed by our state-of-the-art in-house laboratory. Equipped with advanced testing equipment, our lab enables us to conduct rigorous quality control checks throughout the production process.

From raw material analysis to finished product testing, our lab ensures that every Butyl Reclaim Rubber slab meets stringent industry standards. Our team of experienced technicians performs a variety of tests, including:

Chemical Properties Testing (ASTM D297 Standard)
This test evaluates the chemical composition of the Butyl Reclaim Rubber slabs. It involves measuring the percentage of ash, carbon black, acetone extract, and moisture, which provides insights into the purity and composition of the rubber. Additionally, the Rubber Hydrocarbon Content (RHC) is calculated by difference, ensuring that the reprocessed rubber meets strict industry standards.
Specific Gravity Test
This test measures the density of the rubber relative to water. A key indicator of the material's overall uniformity and consistency, specific gravity helps in determining whether the rubber compound has been processed correctly and is free from unwanted additives or fillers.
Tensile Strength Test (kg/cm²)
This test assesses the maximum force the rubber can withstand before breaking. Measured in kilograms per square centimeter (kg/cm²), tensile strength is crucial for ensuring the durability and mechanical performance of the rubber under stress.
Elongation at Break Test
This test measures the extent to which the rubber can be stretched before it breaks. Elongation at break reflects the flexibility and elasticity of the rubber, which is essential for many applications requiring both strength and stretchability.
Mooney Viscosity Test (ML 1+4 @ 100°C)
Mooney viscosity measures the rubber’s viscosity at 100°C, providing a gauge of its processability. The ML (Mooney Large) 1+4 represents the viscosity after one minute of preheating followed by four minutes of testing. It is critical for ensuring that the rubber will behave as expected during processing and molding.
Hardness Test (Shore A)
The hardness of the rubber is tested using the Shore A scale, which measures the resistance of the material to indentation. This test ensures the final product has the correct balance of flexibility and stiffness, vital for its performance in various applications.

By investing in a dedicated in-house laboratory, we are able to maintain a high level of quality control and consistently deliver Butyl Reclaim Rubber products that exceed our customers' expectations.
