CYD product is dendritic structure. Dendritic polymers as "the fourth class of new polymer materials", are attractive to the scientific world and industrial circles. The novelty of these materials includes highly branched molecular structure, a large number of surface functional groups, void space in molecules, monodisperse molecular weight distribution and nanoscale dimensions. The structural characteristics of dendritic polymers lead to unique properties such as excellent solubility and dispersion properties, low melt viscosity and solution viscosity
1 Compared with the same dosage of POE, CYD-6100 can increase the product impact strength by 40-60% in high filler-content PP system.
2 Reduce the formula cost whilemaintaining excellent impact strength.
3 With excellent dispersing and fluidity performance, the melting index is 50% higher than the POE formula.
1 Melt pressure was decreased 200%，Surface property improved,output increased.
2 No negative influence on the products’mechanical properties.
3 No NEGITIVE influence on fire resistance.
The dendritic molecule is a highly branched structure
Dendritic polymers have good geometric symmetry structures and large number of surface groups
The conventional polymer material is a linear or low degree of branching structure
Highly branched structure property of dendrimers makes its high solubility characteristic and ease of processing and application
Highly branched and roughly spherical structures of dendritic polymers lead to less chain entanglement between molecules and have low melt viscosity
The highly branched nature of dendrimers reduces regular array of molecular chains,so dendrimers have low glass transition temperature ,are easy to form film and crystallization performance significantly decreased, such as hyperbranched polyesters can be used in the field with high requirements for transparency
A large number of surface functional groups of dendrimers lead to its high chemical activity and through modifying the end groups, dendrimers can get more functional groups
The traditional materials can not dissolve in many solvents and that limits the applications
The traditional materials generally have a relatively high melt viscosity and are not conducive to processing and application
The traditional polymers are easy to form crystallization due to linear molecular chain structures, such as polyester
