Struktol Launches Additives to Eliminate Odor Issues in Recycled Plastic Applications
In November 2025, Struktol Company of America launched two dual-action additives, RP 17 and RP 53, designed to eliminate unwanted odors in recycled plastics while acting as process aids. These additives enable the use of up to 100% recycled content by ensuring high quality.
Multifunctional Benefits
Beyond odor control, these additives improve filler dispersion, enhance surface finish, minimize mixing times, and decrease plate-out. RP 53 is an advanced odor neutralizer available as an off-white pastille, specifically created to target problematic compounds such as mercaptans, amines, and phosphites. Designed for high-temperature versatility (100° to 130°C) with a specific gravity of 1.07, this additive is crucial for demanding processing conditions in recycling and compounding. The RP 53 additive involves VOC absorption properties, enabling market players to fulfill stringent environmental regulations.
According to Towards Chem&Materials, the mold release agent market size accounted for USD 2.85 billion in 2025 and is predicted to increase from USD 3.04 billion in 2026 to approximately USD 5.36 billion by 2035, expanding at a CAGR of 6.52% from 2026 to 2035 as sectors such as trasportation and manufacturing is rapidly expanding across the globe.
Beyond controlling odor, these additives give significant processing advantages. RP 17 functions as both a mold release agent and process lubricant, which minimizes plate-out and reduces equipment cleaning. Additionally, both products improve filler dispersion, shorten mixing times, and enhance final surface finishes and physical properties.
Industrial Manufacturing Growth Accelerates the Mold Release Agent Market
- The ongoing urbanisation and industrialization, especially in the Asia-Pacific region, are propelling demand for subber plastics and die-casting products.
- The automotive sector is a major driver, with the growing usage of composite materials and lightweight components in vehicles.
- Major market players are emphasising minimizing overall manufacturing costs and defects. High-performance release agents enhance surface finish, ensure smooth removal, and lengthen mold lifespans.
- Rising investments in infrastructure and the adoption of recast concrete materials in emerging economies have substantially increased the demand for concrete release agents.
- Recent advancements in nano-based coatings and bio-based formulations give better performance without causing any harmful effects.
