1. Direct Impact: Ethylene Process PVC (28% of China's capacity; global ~75%)
2. Indirect Impact: Calcium Carbide Process PVC (72% of China's capacity)
3. Market Sentiment & Global Pricing
Oil up → ethylene PVC cost up immediately (big impact if use imported/ethylene resin).
Oil up → carbide PVC cost up gradually (smaller but lasting impact via coal/power/logistics).
Rule of thumb: A 25% oil rise lifts panel cost by 5–12%, depending on resin type and logistics share.
