Quality Assurance
Quality Verification Center: Scientific Data Ensuring Superior Recycled Quality
Our Promise: Quality is the Foundation
As a leading manufacturer of recycled plastic pellets, we understand that quality stability is the cornerstone of your success. Our Quality Assurance Center is equipped with a full suite of precision testing instruments to conduct strict, scientific performance verification on every batch of raw materials. We provide not just raw materials, but a stable, safe, and reliable quality guarantee.
Mechanical Performance & Reliability
These indicators directly determine the durability, load-bearing capacity, and service life of the final product.
| Test Item | Highlight | Significance to Your Product |
|---|---|---|
| Tensile Strength & Elongation | Determines the material's ultimate load-bearing capacity against tensile failure and its plastic deformation capability (toughness). | Ensures your product will not easily break under stress and possesses sufficient flexibility to resist impact or stretching. |
| Impact Strength | Measures the material's ability to resist rapid, sudden impacts and evaluates its brittleness resistance. | Critical for impact resistance and durability, essential for outdoor applications or high-strength products. |
| Flexural Strength & Modulus | Measures the material's resistance (strength) and rigidity (modulus) under bending loads. | Directly affects the support level and resistance to bending deformation of products such as plates, brackets, or casings. |
| Hardness | Evaluates the material surface's ability to resist local indentation, wear, or scratching. | Suitable for products that need to resist daily wear or maintain surface finish. |
Processing & Thermal Performance
These indicators ensure our plastic pellets adapt perfectly to your injection or extrusion processes, achieving optimal production efficiency.
| Test Item | Highlight | Significance to Your Product |
|---|---|---|
| Melt Flow Index (MFI) | Determines the flow rate of plastic in a molten state; it is the gold standard for processing stability. | Ensures the raw material matches your equipment perfectly, avoiding processing difficulties, enabling precise control of product tolerances, and improving production efficiency. |
Composition, Purity & Safety
These indicators are the foundation of quality stability and regulatory compliance, ensuring raw materials are free from impurities and harmful substances.
| Test Item | Highlight | Significance to Your Product |
|---|---|---|
| Heavy Metal Analysis | Strictly tests for eight major harmful heavy metals following international regulations (e.g., RoHS, REACH standards). | Ensures your finished products comply with international environmental directives, allowing smooth export and safe entry into end markets. |
| Ash Content | Strictly measures inorganic residue levels in the material, such as fillers or impurities. | Ensures the purity of recycled pellets meets process requirements, thoroughly eliminating the impact of impurities on product strength and appearance. |
| Specific Gravity | Measures material density; a crucial parameter for formulation optimization and cost estimation. | Ensures density consistency between batches, helping to precisely control volume costs and product weight. |
| Relative Humidity / Moisture Content | Precisely monitors the material's moisture absorption or water content; key to ensuring processing stability. | Prevents defects like bubbles, silver streaks, or performance degradation caused by excess moisture during processing, ensuring finished product quality. |
