SILICA115GR

Silica 115GR is a precipitated white carbon black featuring low specific surface area. While grades 955GR and 975GR deliver strong reinforcing performance, 115GR prioritizes superior flowability and good processability. It is tailor‑made for general‑purpose rubber goods and applications that call for low‑level reinforcement. Manufactured from premium silicate feedstock via mild precipitation, drying and granulation, this product appears as an odor‑free, free‑flowing white loose powder with low caking tendency. It shows favorable compatibility with diverse rubber matrices and eliminates the need for complicated dispersion procedures. It fits mass‑production applications including standard tires, rubber fittings and sealing components.

Its standout benefit lies in outstanding flowability. No extra dispersants are needed throughout the mixing stage. It can incorporate rapidly into rubber compounds with minimal agglomeration and caking, which greatly boosts processing efficiency. Designed with a low specific‑surface‑area profile, it caters to applications requiring mild reinforcement: it will not undesirably raise rubber hardness while preserving the finished product's toughness. Thanks to its low oil‑absorption value, less rubber compound consumption is achieved, bringing down overall manufacturing costs. Its moderate pH keeps rubber vulcanization stable, and helps prevent common defects such as blooming and cracking. Featuring low impurity levels and broad compatibility, it works well with both natural and synthetic rubbers, and is well‑suited for mass production of general‑purpose rubber articles.

Silica 115GR is a precipitated silica with low specific surface area, engineered for rubber formulations requiring moderate‑level reinforcement. Thanks to its outstanding flowability, easy‑processing characteristics and broad substrate compatibility, it is well‑suited for mass‑production of general‑purpose rubber articles, including conventional tires, rubber accessories, seals, rubber hoses, gaskets and common molded rubber goods.

Packaging follows the standard format: 20 kg net weight, lined with inner PE bags and packed in kraft paper sacks. Custom small‑size sample packages are offered. We maintain consistent stock availability, supporting both large‑volume orders and small‑batch trial runs. The product delivers remarkable cost‑effectiveness. Full quality inspection reports can be provided, and technical support is available for adjusting recommended dosage ratios. Our after‑sales team offers timely feedback, addressing practical concerns including proper storage conditions and mixing procedures.

Q1: How does Silica 115GR differ from grades 955GR and 975GR?

Unlike 955GR and 975GR which focus on high reinforcing performance, Silica 115GR is developed for scenarios with low reinforcement requirements. It prioritizes flowability and easy‑processing property rather than strong reinforcement. It avoids raising rubber hardness artificially and maintains finished‑product toughness.

Q2: Which rubber systems and end‑products is 115GR suitable for?

It shows good compatibility with both natural rubber and various synthetic rubbers. It is widely used for mass‑produced conventional rubber goods, such as standard tires, rubber accessories and sealing components.

Q3: What technical documents can you provide? Can you help confirm the addition dosage?

We supply complete quality inspection reports. Our technical team can assist you in adjusting and optimizing addition ratios according to your rubber formula.
