Wansheng Phase II Commissioned: 180,000 Tonnes/Year of Plasticizer Capacity at Wansheng

Shandong Changxing Plastic Additives Co., Ltd. confirms that its wholly-owned subsidiary, Jining Wansheng Environmental Materials Co., Ltd., has commissioned its Phase II project, adding 100,000 tonnes of annual plasticizer capacity on top of Phase I's 80,000 tonnes/year. Wansheng now runs 180,000 tonnes/year of plasticizer capacity, and together with the Changxing headquarters site's 50,000 tonnes/year as per environmental approval, the group's existing plasticizer capacity is 230,000 tonnes/year. This scale 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 produces phthalate-free DOTP plasticizer at 180,000 tonnes/year of commissioned plasticizer capacity, with both phases already operational.

Wansheng Phase II: Project Overview

Wansheng's Phase II project was built and commissioned between 2024 and 2026, on top of the Phase I facility. Key details:

• Project name: Wansheng Phase II Project (万生二期项目)
• Commissioning status: Commissioned and operational
• Phase I capacity: 80,000 tonnes per year of plasticizer
• Phase II capacity: 100,000 tonnes per year of plasticizer
• Wansheng total capacity: 180,000 tonnes per year of plasticizer
• Group existing capacity: 230,000 tonnes per year of plasticizer (Wansheng 180,000 + Changxing headquarters 50,000 as per environmental approval)
• Location: Wenshang Chemical Industrial Park, Jining City, Shandong Province, China
• Feedstock: Recycled PET flakes and post-industrial polyester scrap

Wansheng's Phase I facility delivers 80,000 tonnes per year of plasticizer capacity, and the Phase II project adds a further 100,000 tonnes per year through new distillation columns, refining reactors, and continuous de-alcoholization towers, for 180,000 tonnes per year at the site today.

Readers tracking the group's capacity milestones can refer to our earlier announcement on Wansheng's plasticizer capacity milestone, which documented the commissioning of the Wansheng production lines.

Why Scale? DOTP Supply Security for Global Buyers

The decision to build Phase II reflected several market realities:

1. Growing global demand for phthalate-free plasticizers. Regulatory pressure on ortho-phthalate plasticizers continues to intensify worldwide. Business Research Insights valued the global DOTP market at roughly USD 2.7 billion in 2026 and projects USD 4.7 billion by 2035; at prevailing export prices that equates to annual consumption well above 2 million tons. China accounts for roughly half of global DOTP 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 180,000 tonnes/year of plasticizer capacity means 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. The plant consumes more than 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 Phases

Wansheng has launched two product grades to better serve different application needs:

• First-Grade DOTP (APHA ≤230): 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.

Phase II produces identical product grades to Phase I. Both First-Grade and Superior DOTP are made to the same specifications, under the same ISO 9001/14001/45001/50001 certified management systems. A drum from either phase is the same drum.

In practice, that means you can qualify Wansheng as a supplier today; the product from Phase II is no different from what you receive from Phase I.

Capacity Timeline

The Wansheng capacity build-out ran as follows:

• Mid-2024: Phase I commissioned with 80,000 tonnes/year of plasticizer capacity
• 2024-2026: Phase II constructed, adding new distillation columns, refining reactors, and continuous de-alcoholization towers
• 2026: Phase II commissioned, taking Wansheng to 180,000 tonnes/year of plasticizer capacity

Shandong Changxing and Jining Wansheng supply both phases under one quality system. Buyers interested in securing supply are encouraged to contact our sales team to discuss volume commitments and qualification procedures.

What the Wansheng Capacity Means for Buyers

For procurement managers, Wansheng's commissioned capacity offers several strategic advantages:

Supply security. Wansheng's 180,000 tonnes/year of plasticizer 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, Wansheng's commissioned capacity gives the group room to keep pace with your plans.

Consistent quality. With identical product grades and manufacturing standards across both Wansheng phases, buyers can qualify once and source from either phase with confidence.
