Dendrimer-based glyphosate has better performance.
Dendrimer-based novel formulations of glyphosate has better pesticide effect than commercially available glyphosate, the advantage is to improve the solubility, increase dispersion, protect active substances, increase adhesion and so on. Even under adverse conditions are valid, such as under rainfall conditions, efficacy is still improved by 150% -250%. Nufarm and Starpharma cooperated together to do R & D, produce dendrimer-based substrate to increase or decrease the flow of insecticide penetration-imidacloprid-underground insects, efficient dendrimer-based crop protection products have become the R & D focus of international pesticide manufacturers, and there are always new international patent applications generated. Weihai CY Dendrimer Technology Co. Ltd as the first company in Asia to R&D and produce dendrimers, we have provided many dendrimer products to Peking University, Tsinghua University and Chinese Academy of Sciences, etc. for scientific experiments, and now we have already realized the industrialization of dendrimers. Welcome to the manufacturers of pesticides and other agricultural products to use our dendrimers in efficient crops product development and production to improve performance. Weihai CY Dendrimer Technology Co. Ltd.-Professional Manufacturer for low cost dendritic polymers.

Dendrimers can significantly

Dendrimers can significantly improve the mechanical property of epoxy system.
A small amount of hydroxyl groups of dendrimer (CYD-CR111/CYD-CR236/CYD-CV111/CYD-CV486) react with epoxy curing system to form a three dimensional network structure. Blending with the epoxy system by a simple physical method, due to the special structure of the molecule as well as physical interactions with epoxy matrix, it can significantly improve the mechanical properties of epoxy systems. (1) at low temperature (77 K) hydroxy terminated dendrimers can improve the tensile strength and impact strength of epoxy resins, with mass fraction of 10% of hydroxy-terminated dendrimer, compared to the pure epoxy resin system, the tensile strength increased from the original 98.2MPa to 115.6MPa, increased by 17.7%; failure strain increased with the amount increased of dendrimer, when dosage is 10%, increased from the original 1.9% to 3.1%, increased by 63.2%. (2) the impact strength increased from 25.4 ± 2.7 to 32.0 ± 1.0, increased by 26.0%, and after adding the dendrimer, impact strength at low temperatures is not lower than room temperature, and appropriate dosage of hydroxyl terminated dendrimers does not lower Tg of condensate.

Dendrimers as thermoplastic

Dendrimers as thermoplastic toughening agents have great performance.
Dendrimers (CYD-PR121/CYD-PR256/CYD-PV121/CYD-PV256) as toughening agents for thermosetting material (bismaleimide BMI) have the following advantages: low viscosity, can reduce the processing viscosity of BMI system, ease of processing, more easily compatible with BMI. Methods: Acetylating its active end group by modification, to avoid its reaction with BMI system. BMI + HBP dissolved in allyl phenol solvent, and then stirred and heated to 145 ℃, the clear homogeneous solution was prepared, degassed and added to the preheated mold to solidify, 150 ° C (5 h), 200 ° C (3 h), 250 ° C (3 h). When the dosage of dendrimer is 9%, elongation at break can reach the maximum of 138%, toughening performance was increased by 15.9% compared with linear polyesters, meanwhile, system without dendritic polymers as toughening agent, the elongation at break could not be determined, thus no toughness.

Dendritic metallic

Dendritic metallic nanostructures for fuel cell have good performance.
Fuel cells are new energy conversion technology used in portable electronic devices, stationary power generation and automotive applications, wherein the polymer electrolyte membrane (PEM) fuel cells than conventional fuel battery have the following advantages: flexibility in operating conditions, can quickly change the output power, durable, simple system, so it is the first choice of the car for the power source. The results showed that under the conditions of the PEM fuel cell, the tree platinum sheet than the conventional platinum catalyst has much higher catalytic activity and durability. Under 75 hours at 0.5v, during the test period of constant electric potential use, the performance of platinum black decreased by 47%, while the performance of platinum sheet fell only 33%. More importantly, in the durability test, at 75 hours of operation test, it only declined 19% (1.2A/cm2 to 0.97A/cm2), meanwhile platinum black MEA dropped 43% (1.25A / cm2 to 0.71A/cm2). Dendrimers (CYD-ND193/CYD-ND311/CYD-ND537) have broad application prospects at platinum catalyst for fuel cell due to the durability. Weihai CY Dendrimer Technology Co. Ltd.-Professional Manufacturer for low cost dendritic polymers.
