Our Story
About Purixa
Our Mission
Materials That Make the Difference
Purixa exists to solve the material challenges that others walk away from. Since our founding in 1990, we have built a reputation for tackling complex polymer formulation problems with scientific rigour, creative chemistry, and manufacturing discipline.
Headquartered in Launceston, Tasmania, we combine the agility of a specialist compounder with the analytical depth of a materials research institution. Every product we make is designed to outlast, outperform, and outspecify the standard alternatives.
Our Vision
Shaping the Future of Advanced Materials
We envision a future where high-performance polymer materials are engineered sustainably, produced responsibly, and optimised digitally. Purixa is investing in digital twin formulation modelling, AI-assisted compound development, and closed-loop recycling infrastructure to lead this transformation.
Our goal: to be Australia's most innovative and globally connected polymer materials company by 2030.
Core Values
Built on Six Foundations
01
Scientific Integrity
Every formulation claim is backed by documented data. We don't spec what we can't prove in the lab and on the production floor.
02
Technical Excellence
Our polymer scientists and engineers maintain continuous professional development and deep expertise across the full polymer chemistry spectrum.
03
Client Partnership
We embed our application engineers within client R&D processes. Your problem becomes our problem — and we stay until it's solved.
04
Sustainability
Reducing the environmental footprint of polymer materials is a design criterion, not an afterthought, in every product we develop.
05
Consistency
99.2% on-spec batch delivery rate. Our process control and QA systems are engineered to eliminate variability at source.
06
Innovation
12% of annual revenue reinvested in R&D. We actively co-develop next-generation materials with universities and industry partners.

Case Studies
Solutions That Delivered
Automotive / TPU
Flex-Fatigue Seal for EV Battery Enclosure
A Tier 1 automotive supplier required a seal compound that could withstand 500,000 flex cycles at –40°C to +105°C with zero compression-set drift. Purixa's custom SEBS-TPE compound delivered at cycle 700,000 with <3% set — enabling a 12-month warranty extension for the OEM client.
Result: 40% improvement over client's previous specification →
Medical / Silicone
FDA-Grade HCR Silicone for Neonatal Mask
A medical device manufacturer needed an ultra-soft, skin-safe HCR silicone compound (Shore 20A) meeting USP Class VI and ISO 10993 requirements. Purixa formulated and validated the compound in 8 weeks — passing all biocompatibility tests on first submission, avoiding a 6-month regulatory delay.
Result: First-pass regulatory approval, 8-week development timeline →
Packaging / Biopolymer
Compostable Barrier Film for Fresh Produce
A major supermarket chain's fresh produce supplier required a PLA/PBAT blend film with MVTR <10 g/m²·day — maintaining produce shelf life while achieving EN 13432 compostability. Purixa's GreenMolecule™ BF-22 compound delivered the specified barrier performance with 100% biobased content.
Result: Eliminated 280 tonnes/year of fossil-based packaging →
Oil & Gas / HNBR
Sour-Gas Seal Compound for Offshore Wellhead
An offshore operator required H₂S-resistant wellhead seals rated for 15,000 psi at 180°C. Purixa's HNBR compound, proprietary post-cure process, and special anti-extrusion profile design passed NACE TM0187 sour gas testing with zero failures across 12 seals.
Result: 100% NACE pass rate — zero field failures in 3 years service →
