Dear Sir/Madam,

I hope you are doing well.

I would like to inquire about the availability of **Sliding Graft Copolymer (SGC)**, specifically a **polyrotaxane-based supramolecular polymer composed of cyclodextrin rings threaded onto a polymer backbone and grafted with poly(ε-caprolactone) chains, with pre-crosslinked urethane linkages**.

I understand that a similar material has been reported to be manufactured by **Tianjin Weirui Supra-Molecular Materials Technology Co., Ltd.**, and I am interested in obtaining this material (or an equivalent product) for research purposes.

Could you please provide the following information:

* Availability of this material or a similar product
* Technical datasheet or specifications
* Minimum order quantity (MOQ)
* Pricing and delivery details

Your assistance would be greatly appreciated.

Thank you for your time and support.

Kind regards,
zahid
