WACKER to Increase Its Global Silicone Rubber
Production
Adrian, MI — WACKER is increasing its global production capacities for silicone rubber. With expansion measures at several sites, the compa- ny plans to gradually raise its capac- ities by a total of 44,000 tons (40,000 metric tons) per year, by 2021. Silicone rubber is among the
most sought-after elastomers in the industry. With capacity expansions in the midstream production steps and downstream production, WACK- ER will significantly improve the sil- icone-rubber availability and related service for its customers in the near future. All solid silicone rubber prod- uct groups will benefit from these expansion measures. In April of 2018, WACKER
bought a new production site for sili- cone sealants and thermally conduc- tive silicone compounds on-stream in Jincheon, South Korea. The produc- tion of room-temperature-vulcaniz- ing silicone elastomers and liquid sil- icone rubbers has also started in Amtala, India, where WACKER manufactures silicones in a joint ven- ture with Metroark. Silicone rubber consists essen-
tially of silicone polymers and fillers. They are crosslinked with suitable reactants to produce three-dimen- sional structures that convert the fluid or ductile rubber compound into an elastic rubber. Silicone rubber is flexible at low
temperatures and resistant to heat and aging (UV, ozone and radiation), is easy to process and has good mechanical properties that remain unchanged over a wide temperature range.
Silicone elastomers are used in
areas such as automotive and mechanical engineering, electronics and electrics, textiles, baby articles, toys, household appliances, and sports articles, as well as in the con- struction industry. The WACKER silicone rubber portfolio comprises around 1,000 products. Contact: Wacker Chemical

examples of the integration of hard- ware into security. The cryptographic tasks are delegated to such a medium using PKCS#11 (public-key cryptogra- phy standard) programming. To utilize the API of the secure
memory cards, the manufacturer provides a PKCS#11 library. The API defines the functions required for creating, modifying, using, and delet- ing cryptographic objects on secure flash cards. These objects can be X.509 certificates, RSA private/pub- lic key pairs, elliptical key pairs, symmetrical keys or data objects. A PKCS#11 application program is also supplied. This program allows for all
security functions to be reproduced easily. It uses the PKCS#11 API and implements a command line inter- face to the PKCS#11 library. As a key and certificate man-
agement program, an existing PKCS#11-compatible tool, or the open-source xca tool, an application with GUI for handling X.509 certifi- cates, can be used. xca creates by using the PKCS#11 API requests for certificate signatures, based on pro- tected key material on the card and copies the certificates to it. RSA and ECDSA key pairs can also be created on the card. Using a TPM on a removable flash memory medium as basis for
security solutions with authentication and cryptography is not only cost- effective and independent of other hardware, but also more secure than the conventional TPM approach. Cybersecurity is a constant arms race. It is advantageous to be able to
replace and retrofit security system modules when necessary. Retro - fitting can also come in handy when securing existing products, with min- imal intervention. Contact: Swissbit NA, Inc., 18
