R&D System: Full-Chain In-House Development from Formulation to Sampling

We operate a large-scale in-house R&D laboratory with a dedicated team of professionals, each with over a decade of industry experience. Senior material engineers and chemical formulators account for more than 30% of the team.
Our R&D team is committed to green manufacturing, performance excellence, surface innovation and custom adaptation, focusing on the iteration of eco-friendly leathers, functional leathers, custom-embossed leathers and solvent-free low-odour leathers.
We accept bespoke customisation requests, offering end-to-end R&D services from formulation design to process implementation, while continuously advancing technical exchange and academic research to maintain our technological leadership.

Mass Production

The customer provides specific customisation requirements, including but not limited to target sample physical samples, texture requirements, Pantone colours, and product physical/chemical standards. Both parties conduct in-depth alignment.
PURE's sampling laboratory provides rapid sampling services, delivering the first round of samples within 2 weeks based on requirements. (Special development sampling may take longer.)
PURE sends laboratory samples to the customer, along with internal test reports on colour and physical properties. We collect customer feedback, confirm the sample results, and proceed to pilot run or mass production upon approval.
After sample confirmation, PURE conducts a pilot run to verify mass production quality. (This step is skipped for simple post-treatment adjustments such as colour or texture.) During the pilot run, internal physical property testing is also conducted to ensure the product meets customer requirements.
Once laboratory samples / pilot runs are confirmed, PURE proceeds to mass production and conducts external testing as required. New product development timelines vary depending on material requirements — please contact our dedicated sales team for further details.
