As a Corporate Purchasing Manager you know that every delay or defect eats profit. Below are the three most common pain points reported by over 200 B2B buyers in 2025:
- High Unit Cost: Average LSR price from generic Asian suppliers rose 15 % YoY due to raw‑material shortages.
- Inconsistent Quality: 32 % of buyers reported batch‑to‑batch hardness variation > 5 % SHORE A, leading to failed compliance tests.
- Slow Lead Times: Typical shipping from China exceeds 45 days, while your production schedule demands ≤ 21 days to stay competitive.
According to the Grand View Research LSR market report 2023‑2030, the global market will reach USD 4.97 billion by 2030, driven by demand for precision‑molded, biocompatible parts. If you cannot secure a reliable supplier, you risk losing market share to faster, cheaper rivals.
