Fluororesin Composition Using Melt Flow Ratio to Suppress Agglomeration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compositions containing fluororesins face issues with agglomeration when the proportion of fluororesin is increased, leading to poor appearance in strands.
Innovation Solution
A composition is formulated with a specific ratio of fluororesin A and resin B, where the melt flow rate of resin B is 30 g/10 min or higher, and the ratio of fluororesin A to resin B's melt flow rate is adjusted to 0.2 to 10, enhancing compatibility and preventing agglomeration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the proportion of fluororesin is increased, then the performance benefits of fluororesin are improved, but fluororesin agglomeration occurs leading to poor strand appearance
Solution Approach 1:
The patent applies parameter changes by precisely controlling the melt flow rate ratio between fluororesin A and resin B. By adjusting this parameter to fall within the range of 0.03 to 10, the composition achieves optimal compatibility and dispersion, preventing fluororesin agglomeration while maintaining high fluororesin content for desired performance benefits.
Solution Approach 2:
The patent uses composite materials by combining fluororesin A with specific resin B materials (polyester, polyamide, polyether, or polyolefin resins) in controlled proportions. This composite approach leverages the complementary properties of both materials to achieve uniform dispersion and prevent agglomeration of the fluororesin phase.
2Reliability
If the proportion of fluororesin is increased, then the functional properties are improved, but strand appearance deteriorates due to agglomeration
Solution Approach 1:
The patent controls the melt flow rate ratio parameter to prevent fluororesin agglomeration. By maintaining the ratio (MFR of fluororesin A)/(MFR of resin B) within 0.03 to 10, the composition ensures uniform distribution of fluororesin, resulting in smooth strand appearance while preserving high functional properties through adequate fluororesin content.
Solution Approach 2:
Resin B acts as an intermediary matrix that disperses fluororesin A uniformly. The specific selection of resin B materials (polyester, polyamide, polyether, or polyolefin) and control of their melt flow rate creates a compatible matrix that prevents fluororesin aggregation, ensuring both good appearance and functional performance.

AI summary
The disclosure aims to provide a composition capable of suppressing fluororesin agglomeration, which may lead to strands with a poor appearance, even when the proportion of the fluororesin is increased, and also aims to provide a molded article, a laminate, and a method for producing a composition. The disclosure relates to a composition containing a fluororesin A; and a resin B other than the fluororesin A, the resin B having a melt flow rate of 30 g/10 min or higher at a melting point +8° C., the fluororesin A being a resin satisfying a ratio (a MFR of the fluororesin A)/(a MFR of the resin B)=0.2 to 10.
