Introduction
Why Samples
Come First
A sample request is often the most practical next step after product interest. In the daily chemical industry, customers usually do not evaluate additives by description alone — they need samples to assess viscosity behavior, texture, stability, compatibility, and formulation performance under real development conditions.
At Shandong Landu New Material Co., Ltd., we support sample communication for our daily chemical additive portfolio, including HPMC, HEMC / MHEC, HEC, CMC, and Toothpaste Rheology Additives. This page helps customers understand what can be requested, how to contact our team, and how to prepare for a more efficient sample discussion.

Timing
When to Start
a Sample Request
This page is the right place to start when any of the following applies to your current project stage.
- 1 You have identified a relevant product family and are ready to begin evaluation.
- 2 You need to compare additive directions before committing to a specific grade.
- 3 You want to evaluate viscosity or texture behavior in your own formulation system.
- 4 You are preparing laboratory or pilot testing and need physical material.
- 5 You need technical support before deciding on bulk purchase.
A sample request is most effective when it is connected to a clear application and a clear testing purpose.

Information to Include
To help us recommend a more suitable sample direction, include the following in your message. The more clearly you describe your project, the easier it is for our team to suggest a useful direction.
- Target application — which product type or end-use category
- Product type or family — if already known
- Expected viscosity or texture direction
- Formulation type — aqueous, gel, cream, paste, etc.
- Key testing purpose — viscosity, stability, texture, compatibility, etc.
- Expected quantity after evaluation — if relevant to your sourcing plan
- Destination market or region — if relevant to compliance or specification
The more clearly you describe your project, the easier it is for our team to suggest a more useful and relevant sample direction before testing begins.

Value of Sampling
Why Sample Requests Matter
A strong sample process helps customers move toward sourcing decisions with greater confidence and efficiency.
Reduce Unnecessary Trial-and-Error
Targeted sample communication eliminates guesswork and focuses testing on the most relevant product directions from the start.
Test More Relevant Product Directions
With product recommendation support, customers receive samples that are better matched to their formulation goals.
Improve Formulation Evaluation Efficiency
Pre-test guidance and technical communication help customers get more meaningful results from each evaluation round.
Move Toward Sourcing with Confidence
Customers who complete a structured sample evaluation are better positioned to compare materials and proceed to quotation.
