Resolving White Bloom on Rubber
Client Background
A rubber company observed white bloom on shoe soles after two months of storage. Because the composition of the bloom was unknown, the issue could not be resolved and posed a serious commercial risk.
Solution
WEIPU engineers identified the formulation as the probable cause, developed an analytical plan, extracted and tested the foreign material, and recommended adjustments to improve additive solubility in the rubber compound.
Client Feedback
After implementing the recommendations, the optimized product showed no bloom after six months of storage, gained market acceptance and generated substantial orders.
Ask an EngineerFlame Retardant Formula Analysis
Client Background
A TPE cable manufacturer sought to develop and manufacture its own high-volume flame-retardant system but lacked technical support.
Solution
WEIPU defined the analytical strategy, identified the original flame-retardant components through instrumental analysis, and determined three principal flame-retardant substances to establish a base formulation.
Client Feedback
The client successfully developed the product, generating several hundred thousand yuan in monthly profit.
Ask an EngineerTreatment-Chemical Composition Analysis
Client Background
A major domestic electroplating plant depended on a foreign supplier because critical raw-material information was unavailable and procurement costs and lead times were unfavorable.
Solution
IR, NMR, MS, XRF and GC–MS were used for preliminary identification, followed by Py–GC–MS, GPC, MALDI-TOF and Q-TOF to determine synthetic monomers, molecular weight and molecular structure.
Client Feedback
Using the monomer and molecular-weight data, the client sourced suitable domestic raw materials and prepared to establish in-house synthesis and production.
Ask an EngineerProduct Performance Improvement
Client Background
A manufacturer purchased the same grade of extreme-pressure additive for metalworking fluid from two suppliers but observed a substantial difference in performance.
Solution
WEIPU compared the active content of the same additive grade from both suppliers and assessed its effect on performance.
Client Feedback
Comparative analysis showed a twofold difference in active content; WEIPU recommended sourcing the product with the higher active content.
Ask an EngineerCoating Salt-Spray Testing
Client Background
A client required salt-spray reliability testing for powder coatings applied to 0.2-cm-thick steel sheet intended for coastal markets.
Solution
Based on the intended use, WEIPU recommended a 48-hour neutral salt-spray test, approximately equivalent to two years of natural exposure, to meet both technical and turnaround requirements.
Client Feedback
The product met the specified requirements and was deemed suitable for coastal-market applications.
Ask an EngineerComponent Sample Testing
Client Background
An automotive-component manufacturer needed to evaluate the dielectric breakdown resistance of a hollow cylindrical component with a 2-cm wall thickness.
Solution
After sample preparation and preliminary characterization, WEIPU determined the material and applicable performance range, conducted dielectric breakdown testing using voltage-breakdown and electric-strength instruments, and issued a report with improvement recommendations.
Client Feedback
The client iteratively improved the product based on the report, ultimately met the required standard and secured the contract.
