Polmex

What Polmex does

Polmex is a Western Australian family-owned engineering company that designs, tools, and manufactures medical-grade Liquid Silicone Rubber (LSR) replacement buttons for worn car remote keys. Founded in 1999 and trading online since mid-2008, the company operates from Innaloo (Perth area), Western Australia under ABN 68 443 940 751, with a 9-employee team. The core product line covers more than 30 automotive brands — including Holden, Ford, Toyota, BMW, Audi, Volkswagen, Honda, Hyundai, Jaguar, Land Rover, Mercedes, Saab, Peugeot, Renault, and Subaru — plus accessories for aftermarket car alarm systems (Autowatch, Piranha, Cobra, Dynamco). Adjacent specialty products include keyring loops, silicone shells for car alarm remotes, a Mercedes blanking pin, and an LSR non-return valve for older Onga swimming pool pumps. The underlying technology is medical-grade LSR manufactured using a hot vulcanisation process, with a press-fit button design that snaps over bare switches without glue and requires no reprogramming after installation.

Broad incumbents

• Standard Motor Products: Diversified aftermarket automotive parts manufacturer with engine management, temperature control, and brake product lines. Operates broadly in the same automotive aftermarket space as Polmex, with much larger scale and a focus on higher-ticket mechanical components.
• ACDelco: GM's aftermarket parts brand offering replacement components across vehicle systems. Functions as a broad incumbent in the automotive aftermarket space Polmex addresses, with a focus on OE-equivalent parts for professional and dealer channels.
• Dorman Products: Large aftermarket automotive parts manufacturer and distributor serving the replacement parts market across vehicle systems. Broad incumbent in the same automotive aftermarket category Polmex addresses, though focused on higher-volume mechanical and electronic components rather than silicone consumables.
• AutoZone: Largest US aftermarket automotive parts retailer with thousands of stores and an extensive e-commerce platform. While Polmex operates exclusively online and serves a niche silicone-button product, AutoZone addresses overlapping DIY vehicle-owner demand for replacement parts.
• Advance Auto Parts: Large North American aftermarket auto parts retailer serving DIY and professional installer segments. Broad incumbent in the same addressable market Polmex targets, with overlapping customer demographic but vastly different product focus and scale.
• O'Reilly Auto Parts: Major US aftermarket auto parts retailer with extensive in-store and online distribution. Comparable to Polmex in serving vehicle owners seeking DIY replacement alternatives to dealer service, though at vastly larger scale and broader product portfolio.

Others

• Wacker Chemie: Major global manufacturer of silicone products including LSR raw materials used in medical, automotive, and industrial applications. Relevant as an upstream silicone material supplier to Polmex's medical-grade LSR hot-vulcanisation manufacturing process.
• Momentive Performance Materials: Specialty silicones and materials manufacturer producing LSR and other elastomers for industrial and consumer applications. Relevant as an upstream silicone materials supplier to Polmex's LSR hot-vulcanisation manufacturing process and a benchmark for silicone input pricing.
• Shin-Etsu Chemical: Global chemical company and one of the largest silicone rubber manufacturers worldwide. Relevant as a potential upstream supplier of medical-grade LSR and a comparator for silicone materials economics that affect Polmex's input costs.
