How we work
Application research connected directly to production.
The company profile describes a cross-functional organization spanning formulation, manufacturing, quality, technical engineering and customer response. This structure keeps material development connected to real substrates, dispensing methods, cure conditions and reliability targets.
Manufacturing discipline
Controlled raw-material handling, batch weighing, mixing, filling and production records support repeatable manufacturing.
Technical response
Application engineers help evaluate substrates, dispensing, cure profiles and validation requirements before production adoption.
R&D + PRODUCTION
Silicone expertise with roots in Korea and manufacturing in Yantai.
EST originated from E.S.T. Co., Ltd. in South Korea, established in 1999. In 2005, Yantai EST Silicone Technology Co., Ltd. was established in China together with a materials research and development center.
The company develops silicone ink, thermal-management materials, sealants, protective materials, functional silicone materials and specialty silicone resins for textiles, electronics, semiconductors, mobility and new energy applications.
Inside EST
From controlled materials to production-ready supply.
Actual EST facilities and operating scenes show the path from incoming materials and measured batching to laboratory verification and finished-goods shipment.
01Raw-material control
Organized storage and identified material zones support controlled handling before production.
02Measured batching
Production weighing links formulation requirements to repeatable batch preparation.
03Laboratory verification
Formulation and test equipment support development, comparison and process validation.
04Packing & shipment
Finished materials are packed for handling and onward customer delivery.
Quality & complianceISO 9001Quality management system referenced in the company profile. ISO 14001Environmental management system referenced in the company profile. RoHS & REACHMaterial testing and compliance support for applicable products. UL & OEKO-TEXSelected material systems are supported by product-specific certifications. Certification and test scope is product-specific and should be confirmed against the current certificate or TDS before use.
Quality and compliance pathway
The company profile records ISO 9001 and ISO 14001 certification, RoHS and REACH testing, with selected products supported by UL and OEKO-TEX certification.
Connected expertise
One workflow across research, quality and the customer line.
EST's working model brings technical roles together around the application rather than handing off a generic product list.
