Shandong Changxing Plastic Additives Co., Ltd. announces that its wholly-owned subsidiary, Jining Wansheng Environmental Materials Co., Ltd., will break ground on a new Phase II expansion project in October 2027. The project will add approximately 80,000 tons of annual DOTP capacity, increasing Wansheng's total production capability from 150,000 tons to 230,000 tons per year. The added capacity grows the group's output of recycled PET-based DOTP and gives global PVC manufacturers more supply headroom.
If you are a procurement manager or PVC manufacturer weighing long-term supply partners, here is the short version: Wansheng plans to keep scaling output of phthalate-free DOTP plasticizer as global demand grows.
Wansheng Phase II Expansion: Project Overview
The Wansheng Phase II expansion project is an independent new construction project, distinct from the Phase II workshop that was commissioned between 2024 and 2026 as part of the original 150,000-ton facility. Key details:
- Project name: Wansheng Phase II Expansion Project (万生二期扩建项目)
- Construction start: October 2027
- Additional capacity: Approximately 80,000 tons per year of DOTP
- Post-expansion total capacity: Approximately 230,000 tons per year
- Location: Wenshang Chemical Industrial Park, Jining City, Shandong Province, China
- Feedstock: Recycled PET flakes and post-industrial polyester scrap
The current Wansheng plant operates at 150,000 tons per year, a figure that already includes the Phase II workshop completed in recent years. The new Phase II expansion adds 80,000 tons of independent capacity on top of that facility.
Readers tracking the group's capacity milestones can refer to our earlier announcement on Wansheng's 150,000-ton DOTP capacity milestone, which documented the commissioning of the current production line. The Phase II expansion described on this page is the latest update to the subsidiary's growth plan.
Why Expand? DOTP Supply Security for Global Buyers
The decision to expand reflects several market realities:
1. Growing global demand for phthalate-free plasticizers. Regulatory pressure on ortho-phthalate plasticizers continues to intensify worldwide. Global annual DOTP consumption exceeds 2.5 million tons, and China accounts for roughly 55 percent of global production capacity. DOTP, as a proven non-phthalate alternative, is seeing sustained demand growth across PVC applications: cables, flooring, food-contact films, and medical devices.
2. Supply chain resilience. The COVID-19 pandemic and subsequent logistics disruptions highlighted the vulnerability of just-in-time supply chains. Wansheng's expanded capacity should mean longer-term supply continuity, shorter lead times, and more room to absorb demand swings. Buyers can check the operation first-hand on a Wansheng factory tour.
3. Circular economy. Wansheng turns waste PET into high-performance DOTP, which fits what sustainability-minded buyers now ask for. After expansion, the plant will consume noticeably more than its current 40,000+ tons of waste material per year, keeping more textile and plastic waste out of landfills.
Product Consistency: First-Grade and Superior DOTP Across Both Facilities
Wansheng has recently launched two product grades to better serve different application needs:
- First-Grade DOTP (APHA ≤200): Optimized for general industrial PVC applications including cables, flooring, artificial leather, and industrial films.
- Superior DOTP (APHA ≤150): Engineered for premium applications such as food-contact packaging, medical devices, children's products, and high-end consumer goods. See our dual-grade DOTP system guide for the full specification comparison.
The Phase II expansion factory will produce identical product grades to the current Wansheng plant. Both First-Grade and Superior DOTP will be made to the same specifications, under the same ISO 9001/14001/45001/50001 certified management systems. A drum from either plant is the same drum.
In practice, that means you can qualify Wansheng as a supplier today; the product from the expanded facility will be no different from what you receive now.
Phase II Expansion Timeline and Next Steps
The project timeline is as follows:
- October 2027: Groundbreaking and construction start
- 2028-2029: Construction and equipment installation
- 2029-2030: Commissioning and ramp-up to full production
Shandong Changxing and Jining Wansheng will provide updates as the project progresses. In the meantime, buyers interested in securing supply from the expanded facility are encouraged to contact our sales team to discuss volume commitments and qualification procedures.
What the DOTP Capacity Expansion Means for Buyers
For procurement managers, the Wansheng Phase II expansion offers several strategic advantages:
Increased supply security. The additional 80,000 tons of capacity significantly reduces the risk of supply disruptions, particularly during periods of high demand or unexpected facility outages.
Scalable partnership. If your own volumes are set to grow, the expanded capacity gives Wansheng room to keep pace with your plans.
Consistent quality. With identical product grades and manufacturing standards across both the current and expanded facilities, buyers can qualify once and source from either plant with confidence.
When will the Wansheng Phase II expansion project begin construction?
The Wansheng Phase II expansion project is scheduled to break ground in October 2027. The new 80,000-ton DOTP production line will be added to the existing 150,000-ton facility, bringing the plant's total annual capacity to approximately 230,000 tons.
What is the current DOTP capacity at Wansheng before the Phase II expansion?
Wansheng currently operates a 150,000-ton-per-year DOTP production line. This includes the Phase II workshop that was commissioned between 2024 and 2026. The new Phase II expansion project is an independent additional expansion, distinct from the already-operational Phase II workshop.
How much additional DOTP capacity will the Phase II expansion add?
The Phase II expansion will add approximately 80,000 tons of annual DOTP capacity. This will increase Wansheng's total capacity from 150,000 tons to approximately 230,000 tons per year.
Will the Phase II expansion factory produce the same product grades as the current Wansheng plant?
Yes. Wansheng has launched two product grades: First-Grade DOTP and Superior DOTP. The Phase II expansion factory will maintain identical product grades and quality standards as the current Wansheng plant, so customers get the same product from either facility.
What feedstock will the new Phase II expansion facility use?
The new facility will continue Wansheng's circular-economy approach, converting waste PET flakes and post-industrial polyester scrap into high-purity DOTP through catalytic esterification and transesterification, consistent with the plant's existing operations.
How does the Phase II expansion improve supply security for global buyers?
The extra 80,000 tons means more supply security and shorter lead times for buyers facing demand swings. It also scales the group's DOTP base from 150,000 tons at Wansheng today to about 230,000 tons by 2030.
