We are a China-based R&D and manufacturing enterprise. Our current product portfolio includes 1,3-diethynylbenzene (m-diethynylbenzene, CAS: 1785-61-1) and 2,2'-[[2-(oxiranylmethoxy)-1,3-phenylene]bis(methylene)]bisoxirane (CAS: 13561-08-5). Custom manufacturing and OEM processing services are available for cooperation. Our main application areas are as follows: Polyarylacetylene (PAA) resin — ablation-resistant composites for aerospace, our largest downstream application Silicon‑arylacetylene hybrid high-temperature resistant resin for semiconductor and electronic packaging Synthetic building blocks for conjugated organic optoelectronic materials, liquid crystals and graphdiyne carbon materials Intermediates for pharmaceutical and macrocyclic molecule synthesis Copolymerization with other alkynes to produce high-performance thermosetting resins We welcome enquiries for both standard products and custom synthesis projects. - @yangzheng395
